Answer 1

Niacin, also known as Vitamin B3 or Nicotinic acid, is part of the Vitamin B ( option 2) complex group of water soluble vitamins, and is essential for cell metabolism.

Step-by-step explanation:

Niacin, also known as Nicotinic acid or Vitamin B3, falls under the category of Vitamin B. Niacin is one of the water soluble vitamins that is part of the B-complex group, which includes diverse vitamins like Thiamine (B₁), Riboflavin (B₂), Niacin (B3), Pantothenic Acid (B5), Vitamin B6, Biotin (B7), Folic Acid (B9), and Cobalamin (B₁₂). Niacin specifically has the chemical name of nicotinic acid, and it contains a pyridine ring with a carboxylic acid. It is also converted into its amide form called niacinamide or nicotinamide. These B vitamins play essential roles in cell metabolism and are crucial for maintaining good health.
