Which one is wrongly matched

Options

A. Niacin-Pellagra
B. Vitamin K - Sterility
C. `B_(1)`-Beri-beri
D. None of the above

Answer

To determine which option is wrongly matched, we will analyze each of the given options in the question:

1. **Niacin and Pellagra**:
- Niacin, also known as vitamin B3 or nicotinamide, is a part of the vitamin B complex.
- A deficiency in niacin leads to a disease called pellagra, which is characterized by symptoms such as diarrhea, dermatitis, and dementia.
- Therefore, this match is **correct**.

2. **Vitamin K and Sterility**:
- Vitamin K, known as phylloquinone, plays a crucial role in blood clotting.
- A deficiency in vitamin K can lead to prolonged bleeding due to impaired blood clotting mechanisms.
- However, sterility is not caused by a deficiency in vitamin K; instead, it is associated with a deficiency in vitamin E (tocopherol).
- Thus, this match is **incorrect**.

3. **Vitamin B1 and Beriberi**:
- Vitamin B1, also known as thiamine, is essential for carbohydrate metabolism.
- A deficiency in vitamin B1 leads to beriberi, which manifests as symptoms like loss of appetite, fatigue, and neuritis.
- Therefore, this match is **correct**.

4. **None of the Above**:
- This option suggests that all the matches are correct, which is not the case since we identified one incorrect match.

Based on the analysis, the wrongly matched option is **Vitamin K and Sterility**.

### Final Answer:
The wrongly matched option is **Vitamin K and Sterility**.
