Explanation:
The receptors located in the heart, aortic arch, and carotid sinuses that trigger autonomic reflexes in response to fluctuations in blood pressure are known as Baroreceptors.
Baroreceptors are present in the carotid sinus and the aortic arc and regulate the blood pressure levels in the body. Whenever blood pressure increases or decreases the stretch receptors present in the blood vessels send signals to the brain.
The brain interprets them and send signals to other parts of the body like kidney and heart. The kidney and heart releases enzyme like erythropoietin and atrial natriuretic factor respectively that regulate the blood pressure accordingly.

Drugs are substances resulting in physiological changes. A basic drug; low pH will result in urinary excretion but not urinary reabsorption. Thus, option b is correct.
<h3>What is urinary excretion?</h3>
Urinary excretion is the process of eliminating the waste substance from the body through urine. It is majorly done by the kidneys and their structural unit called nephrons.
The basic drug with low pH will be excreted from the body and will not be reabsorbed as urine has low pH with acidic conditions. The basic drugs undergo changes and get expelled from the body.
Therefore, option b. basic drug with low pH gets excreted.

During external chest compression on children under 8 years old the sternum should be compressed about 1/3 to 1/2 the depth of the chest.
<h3>What is the correct chest compression for a child?</h3>
Cardiopulmonary resuscitation is known as CPR. When a child's respiration or heartbeat stops, it is a life-saving surgery.
Compress the breastbone. For a baby or infant, press down 4 or 5 cm, or around one-third of the chest's diameter. At a rate of around 100–120 compressions per minute, quickly release the pressure before repeating. When we've completed 30 compressions, tilt the head, elevate the chin, and take two deep breaths. For adults, compress the chest to a depth of at least 2 inches. Allow the chest to fully rise each time. These compressions must be swift, forceful, and uninterrupted.
