Answer 1

Correct answer is (c) Vitamins contain amino groups

To explain: Plants can synthesize almost all vitamins, and are considered essential food factors. Both deficiency and excess of vitamins affect the health of an individual negatively. Vitamins were earlier identified as compounds containing amino groups, but was later discovered that most of them did not contain amino groups.
