Answer:
D. provitamin.
Explanation:
A provitamin is a substance that the body can transform into an active vitamin through metabolic processes. If compared with vitamins, provitamins have no biological activity or are much lower. In other words, provitamins are vitamin precursors.
Although not very frequent, sometimes you can see the term previtamin used as a synonym.
For example, beta-carotene, the most abundant carotenoid in nature, has about one sixth of the biological activity of retinol, or vitamin A, but can be transformed into retinol in the liver by an enzymatic reaction.
