Which of the following is mismatched

Options

A. Vitamin K - Beri-beri
B. Vitamin C - Scurvy
C. Vitamin A - Xerophthalmia
D. Vitamin D - Rickets.

Answer

To determine which of the following options is mismatched, we need to analyze each vitamin and its associated deficiency disease:

1. **Vitamin K - Beriberi**:
- Vitamin K is essential for blood clotting and its deficiency can lead to bleeding disorders, especially in newborns.
- Beriberi, on the other hand, is caused by a deficiency of Vitamin B1 (thiamine).
- Thus, this pairing is incorrect.

2. **Vitamin C - Scurvy**:
- Vitamin C (ascorbic acid) is crucial for collagen synthesis and its deficiency leads to scurvy, which is characterized by symptoms like bleeding gums and fatigue.
- This pairing is correct.

3. **Vitamin A - Xerophthalmia**:
- Vitamin A is vital for vision, and its deficiency can lead to xerophthalmia, which is a condition that can cause blindness.
- This pairing is correct.

4. **Vitamin D - Rickets**:
- Vitamin D is important for calcium absorption and bone health. Its deficiency leads to rickets in children, characterized by weak or soft bones.
- This pairing is correct.

Based on the analysis above, the mismatched option is:

**Correct Answer: Vitamin K - Beriberi**
