submit

Explanation:

When too cold, the body tries to retain heat. Goosebumps (from hair erector muscles) and vasoconstriction (narrowing blood vessels to reduce heat loss) occur. Sweating cools, vasodilation releases heat—both are for warmth loss, so incorrect.

Answer:

B. Goosebumps and vasoconstriction.
