2) C

A – Wrong
The word ‘need’ indicates that this statement is a bit too strong and hence should not be the answer.

B – Wrong
The text clearly suggests that some groups of people are unable to produce vitamin D efficiently. Therefore, sunlight definitely is not the best way to obtain vitamin D.

C – Correct
Even though this statement may seem too specific as the text also mentions other groups of people, but in fact, this is the best statement out of all the options given. Also, the hint lies in the first line of the second paragraph. “Based on these finding…pale-skinned people…vitamin D supplements” suggest that this is the conclusion of the text.

D – Wrong
No mention of skin cancer in the text

E – Wrong
We cannot determine who needs the vitamin D supplements more.
