Which lifestyle factor combination is most associated with the need for vitamin D supplementation according to the material?

Explanation:
Vitamin D status hinges on two main sources: sun-driven production in the skin and dietary intake, especially from fortified foods like dairy. When someone has limited sun exposure and also avoids dairy, both primary avenues for getting vitamin D are reduced. That combination leaves a person more likely to be deficient, making supplementation more likely needed. Outdoor activity increases sun exposure and helps the body make vitamin D, while dairy avoidance removes a common fortified dietary source, so those patterns reduce the need for supplements rather than increase it. High protein intake doesn’t directly guarantee adequate vitamin D, and excessive sunlight isn’t a reason to require supplementation.
