When the skin is exposed to ultraviolet rays, the skin produces a molecule that is turned into Vitamin D.
Sun is the source of ultraviolet rays important for Vitamin D production. Due to this reason, in the case of Vitamin D deficiency, it is recommended by doctor's to absorb sunlight by skin. The Vitamin D production occurs specifically by UV B rays rays which lie in the range of 290-315 nanometer.
The chemical 7-dehydrocholesterol absorbs these rays and convert to previtamin D3. Further, previtamin D3 isomerizes to Vitamin D. Other than sunlight, Vitamin D can be taken through diet. The sources include seafood like fish, fish oil, dairy products, beef liver etc. Vitamin D is required for bone and teeth formation, muscle contraction, immune system etc.

Answer:
C. A Catholic woman who fasts on Good Friday to honor religious custom.
Explanation:
Today, many people carefully consider what they eat before consuming it according to his or her values, in contrast to choosing what to eat only by cravings or 'superficial' decisions. For example, choosing to consume less meat due to the impacts that the meat industry has in our climate is a decision someone makes in regard to values, not only nutrition. So, there is much more analysis involved in this type of decisions.
In this scenario, a Catholic woman decides to fast on Good Friday because she is honoring her religion. This is not a nutrition or health choice, this is a conscious decision based on her values. On the other hand, the other options refer to decisions they make in regard to taste, cravings, or diet.
