Which one is correctly matched?

Options

A. Vitamin - E : Thiamine
B. Vitamin - D : Riboflavin
C. Vitamin - `B_(1)` : Tocopherol
D. Vitamin `-B_(12)`: Cyanocobalamine

Answer

To determine which option is correctly matched, we need to analyze the vitamins and their corresponding names.

1. **Identify the Vitamins and Their Names**:
- Vitamin E is known as **tocopherol**.
- Vitamin D is known as **calciferol**.
- Vitamin B1 is known as **thiamine**.
- Vitamin B2 is known as **riboflavin**.
- Vitamin B12 is known as **cobalamin**.

2. **Evaluate Each Option**:
- **Option A**: States that Vitamin E is called thymine. This is incorrect because Vitamin E is tocopherol, and thymine is a nucleotide base, not a vitamin.
- **Option B**: States that Vitamin D is known as calciferol. This is correct.
- **Option C**: States that Riboflavin is known as Vitamin B complex. This is misleading because riboflavin is specifically Vitamin B2, while Vitamin B complex refers to a group of several B vitamins.
- **Option D**: States that Vitamin B1 is tocopherol. This is incorrect because Vitamin B1 is thiamine.

3. **Conclusion**: The only correctly matched vitamin is **Vitamin D as calciferol**.

**Final Answer**: The correctly matched option is Vitamin D is known as calciferol.
