Answer:
Common causes of blindness are diabetic neuropathy, glaucoma and cataracts.
Explanation:
Blindness refers to the complete lack of functional vision.It occurs when an inadequate amount of light hits the retina, or the information has not been delivered to the brain correctly.
Complete blindness : characterized by a complete and total loss of vision. Merck Manuals reports that legal blindness is defined as having equal to or worse than a 20/200 visual acuity in the better eye. Having a visual acuity of 20/200 means that someone with normal vision can see an object at 200 feet, and a person with impaired vision can see at a distance no further than 20 feet. Several different diseases can cause complete blindness; some develop later in life and some are present at birth. The leading cause of blindness in the United States is diabetes, according to the National Eye Institute. Diabetes causes diabetic retinopathy, which results in destruction of the retina. Other causes of complete blindness include age-related macular degeneration, which the National Eye Institute calls the most common cause of blindness in adults who are 60 or older; cataracts, which obstructs light from hitting the retina because of opaque patches on a lens; and glaucoma, which causes blindness due to damage to the optic nerve.
Color Blindness
:
People who have color blindness, also called dyschromatopsia, are unable to distinguish certain colors. This type of blindness more commonly affects men than women. Merck Manuals reports that the most common form of color blindness is red-green color blindness, which makes it difficult to distinguish certain shades of red and green. Color blindness is almost always present at birth, and is usually caused by the presence of a defective gene on the X chromosome. The reason that more men are affected by color blindness than women is that women have two X chromosomes; thus, even if they are "carriers" of a bad gene, their other X chromosome usually has a functional gene. Because men have only one X chromosome, the presence of one bad gene is sufficient to cause color blindness. Defective retinal cells result in some forms of color blindness; other forms are caused by defects in the optic nerve.
Night Blindness
:
Night blindness is vision impairment that occurs at night or when light is dim. It does not generally result in a complete lack of vision but significantly impaired vision. People with night blindness often have difficulty driving at night or seeing stars. Several different factors cause night blindness, according to the University of Maryland Medical Center. These factors include cataracts, birth defects, a vitamin A deficiency, or a retinal disease called retinitis pigmentosa
C-reactive protein (CRP) is an acute phase protein found in trace amounts in normal serum.
<h3>What is C-reactive protein (CRP)?</h3>
- C-reactive protein (CRP) is a ring-shaped pentameric protein found in blood plasma, whose concentrations increase due to irritation and inflammation.
- It is an acute-phase protein of originating in liver that rises in concentration after interleukin-6 discharge by macrophages and T cells.
- A C-reactive protein test checks for irritation in the body. Irritation can be brought about by contamination, injury, or constant illness.
- A C-reactive protein (CRP) test estimates the degree of C-reactive protein in your blood. Your liver deliveries CRP into your circulatory system in light of irritation.
- Medical services suppliers utilize this test to help analyze and screen a few unique reasons for irritation, like diseases and certain immune system conditions.
- A CRP test result of 1.0 to 10.0 milligrams per deciliter (mg/dL) is for the thought to be a reasonably high level.
- This outcome might demonstrate any of the accompanying conditions like inflammation due to rheumatoid arthritis, cardiovascular failure (myocardial localized necrosis), pancreatitis, bronchitis.
- A CRP test consequence of in excess of 10 mg/dL is thought to be a marked increase in CRP.
- This outcome might demonstrate any of the accompanying circumstances like intense bacterial diseases, viral contaminations, systemic vasculitis, significant injury or trauma.

Answer:
(D). cesarean section
Explanation:
Oxytocin is a peptide hormone, synthesized by hypothalamus and secreted by posterior pituitary. Oxytocin plays role in sexual reproduction, lactation, and induce contractions during child birth.
Oxytocin is naturally produced at the time of child birth, but natural oxytocin has a short half-life. Hence, oxytocin infusion is done during child birth or cesarean section as it maintains contraction of uterine wall during the surgery.
Thus, the correct answer is option (D).
