The Correct Option is A
Solution and Explanation
Step 1: The image shows a painful skin rash with grouped blisters confined to a localized band, the typical appearance of herpes zoster (shingles).
Step 2: Shingles results from reactivation of the varicella zoster virus (VZV) within the body. The initial infection with VZV causes chickenpox; after it resolves the virus stays dormant in nerve cells.
Step 3: On reactivation the virus travels along the nerve from the ganglion to the skin endings, producing the characteristic dermatomal blisters. Risk factors include old age and poor immune function.
Step 4: Chickenpox and smallpox give widespread (centripetal or centrifugal) lesions, not a single dermatomal band, and atopic dermatitis is an itchy eczematous rash without grouped vesicles in a dermatome. Hence the picture is herpes zoster.
