Which of the following is a function of vitamin B-6 (pyridoxine)?

Explanation:
Vitamin B-6 (pyridoxine) serves as a coenzyme in a wide range of reactions involved in amino acid metabolism, enabling transamination, decarboxylation, and other steps that convert amino acids into biologically useful forms. This ties directly to protein and amino acid metabolism and also supports the synthesis of neurotransmitters, which can influence PMS symptoms. That connection to PMS relief is why this option is the best choice. The other vitamins align with different roles: maintaining vision is mainly vitamin A, regulating blood calcium is vitamin D, and collagen synthesis depends on vitamin C.
