Explanation:

The text states that people should use sunscreen and/or protective clothing to prevent from the sun (implied to prevent skin burning or diseases from excessive sun). Option C says "prevent their skin from burning", which aligns with the purpose of using sunscreen and protective clothing to avoid skin damage from the sun. Option A is incorrect as the text says people absorb vitamin D from sunlight, not that they should absorb more. Option B is incorrect as the text says to limit time in the sun, not limit serotonin. Option D is about improving mood, which is not related to wearing sunscreen/protective clothing.

Answer:

C. prevent their skin from burning
