Question

how often does the body need b vitamins and vitamin c to be consumed?
a. every one to three days
b. once a week
c. every few weeks
d. the body can synthesize these

Explanation:

B vitamins and vitamin C are water - soluble vitamins. The body does not store them in large amounts, so they need to be consumed regularly. Typically, the body needs these vitamins every one to three days to maintain proper levels for metabolic and other bodily functions. Option a matches this requirement. Option b (once a week) and c (every few weeks) are too infrequent as the body can't store enough of these water - soluble vitamins for that long. Option d is incorrect as the question is about consumption frequency, not synthesis.

Answer:

a. Every one to three days
