The Correct Option is A
Solution and Explanation
Step 1: Cutis marmorata is a transient skin change in which the skin develops a pinkish-blue mottled or marbled pattern. It is common in infancy and is seen in about half of children.
Step 2: The trigger is exposure to cold temperature. Cold causes the superficial small blood vessels of the skin to dilate and constrict unevenly at the same time, producing the reticulated marbled appearance.
Step 3: The change is physiological and reversible. Rewarming the skin restores its normal colour. This points to cold temperature as the cause (option a) and rules out dust, heat and humidity (options b, c and d), which do not produce this vascular mottling.
