Solution

The true statement is: "Skin can form prohormone vitamin D after being exposed to sunlight."

Here's why:

  1. Vitamin D is not necessary for proper collagen formation. Vitamin C is the one that's necessary for collagen formation.
  2. Skin can indeed form prohormone vitamin D after being exposed to sunlight. This is how our body naturally gets most of its vitamin D.
  3. Excessive intakes of vitamin D do not cause rickets in children. On the contrary, rickets is caused by a deficiency of vitamin D, calcium, or phosphate.
  4. Pellagra is not a vitamin D deficiency disorder in adults. It's caused by a deficiency of niacin, also known as vitamin B3.
