Option (b) is correct i.e. pediculosis, contagious disease creates a primary skin lesion that is a pinpointed macule, papule, or wheal with hemorrhagic puncture site.
Most infections of head lice i.e. pediculosis are symptomless. When symptoms are present, there may be irritation, a tickling sensation as though something is moving in the hair, and itching due to an allergic reaction to louse saliva. One potential source of problems is secondary bacterial infection. The pathogens that cause Bartonella quintana, Rickettsia prowazekii, and Borrelia recurrentis body lice are a vector for (louse-borne relapsing fever). The most common way that head lice are transmitted is through contact with an infected person (i.e., head-to-head contact). During play (sports, playgrounds, summer camp, and sleepovers), at home, school, and in the community, there is frequently contact. Less frequently, it is possible for flies to transmit head lice (more common with body lice). Transmission can also occur if you use infected combs, brushes, towels, or if you lie on a bed, couch, pillow, carpet, or stuffed animal that has recently come into contact with an infected person.

TLDR: Antibiotics must be taken several weeks to fully kill the bacteria. Else, surviving bacteria develops drug resistance.
Antibiotic prescription really depends on the patient's condition. Some conditions like major surgery or diseases that cause immunosuppression are more prone to bacterial infection, thus they must take antibiotics for prolonged periods of time to fight their current infections or prevent further infections.
Antibiotics, as a general rule, must be given 7 days or several weeks (depending on the bacteria/pathogen) to be sure that all the disease-causing bacteria are dead. If the drugs are taken only until symptoms fade, the surviving bacteria (now fewer in number and not causing symptoms) will develop mutations that may help resist the previously-taken antibiotic, giving rise to drug resistance.
Thus, Arjun must take the antibiotics for several weeks more (according to the doctor's orders, of course) to kill all remaining bacteria and also to prevent bacterial drug resistance. Which is really problematic, since we're slowly losing our number of effective antibiotics.

What is the movement of substances from the blood into the proximal tubule?
- In the urine of experimental rodents and humans (eating a Western-style diet), urea is the most prevalent solute.
- In comparison to plasma and extracellular fluids, it is significantly more concentrated in urine.
Which part of the tubule is permeable to water only under the influence of ADH?
- ADH operates on the distal tubules and collecting ducts, increasing their water permeability to counterbalance that shift.
- Reabsorbing water as a result lowers blood osmolarity, concentrates urine, and decreases urine volume.
What does white cells in urine mean?
- If your doctor performs a urine test and discovers an excessive number of leukocytes, this may indicate an infection.
- White blood cells called leukocytes assist your body in battling pathogens.
- It's frequently a symptom of a problem somewhere in your urinary tract when you have more of them than usual in your urine.
