The Correct Option is C

Cobalt is an essential element and is a key constituent of Vitamin B12, also known as cyanocobalamin. Vitamin B12 is crucial for the production of red blood cells, nerve function, and DNA synthesis.
- Vitamin D: This vitamin does not contain cobalt. It is primarily involved in calcium absorption and bone health.
- Vitamin C: Vitamin C (ascorbic acid) does not contain cobalt. It is important for collagen formation and immune function.
- Vitamin B12: Correct! Vitamin B12 contains cobalt at the center of its structure, making it unique among vitamins. It is essential for various biological functions, including red blood cell production.
- Folic acid: This vitamin does not contain cobalt. It is vital for DNA synthesis and the formation of red blood cells. Thus, the correct answer is (3) Vitamin B12.
