Your old friend from high school has just moved to Northern Canada to do full-time research on bats in caves. She typically works in the caves during the day when the bats are there and leaves at sundown when the bats are active. Your friend is careful about her health and only purchases organic and all natural foods. Based on this information alone, which of the following foods would you recommend your friend regularly buy at the grocery store? a. Whole-grain bread
b. Vitamin D-fortified milk
c. Vitamin A-fortifie
d carrot juiced. Wheat germ
e. Vitamin K-rich whole grain cereals

The correct answer is - option B.  Vitamin D-fortified milk

Explanation:

At the point when your skin is presented to daylight, it makes vitamin D from cholesterol. The sun's UV or ultraviolet B (UVB) rays hit cholesterol in the skin cells, giving the vitality to nutrient D synthesis.

Vitamin D is an essential nutrient that helps in bone strength and hardness of bones and prevents various diseases and helps in calcium absorption. As it is known that the researcher spends her most of day time inside the cave she can not synthesis vitamin D naturally. Thus, Vitamin D-fortified milk is best for her bones and absorption of calcium as it has added vitamin D to it.

Thus, the correct answer is - option B.  Vitamin D-fortified milk
