Show Solution
The Correct Option is A
Solution and Explanation
Step 1: The clue is in the word "marmorata", meaning marble-like. The skin shows a lacy, blue-pink network, mostly in babies, and the question asks what brings it on.
Step 2: The provoking factor is chilling of the skin. When the surface gets cold, the tiny dermal vessels respond unevenly - some dilate while others constrict - and this patchy vasomotor response paints the mottled reticular pattern across the skin.
Step 3: Because it is a cold-induced vascular reflex, simply warming the child makes it disappear, confirming it is benign. Dust, heat and humidity do not generate this constrict-dilate mismatch, so they are not the cause.
\[\boxed{\text{Cold temperature}}\]
