D. I and II

Answer

To solve the question, we need to evaluate each statement regarding the diseases and their associated vitamin deficiencies.

### Step-by-Step Solution:

1. **Evaluate the first statement:**
- **Statement:** Hypoprothrombinemia is caused due to deficiency of vitamin K.
- **Analysis:** Hypoprothrombinemia is indeed caused by a deficiency of vitamin K, which is essential for blood clotting. Therefore, this statement is **correct**.

2. **Evaluate the second statement:**
- **Statement:** Dermatitis is caused due to deficiency of riboflavin.
- **Analysis:** Dermatitis is typically associated with a deficiency of vitamin B2 (riboflavin), but it can also be caused by deficiencies in other vitamins, such as vitamin D. However, the primary association for dermatitis is not riboflavin. Therefore, this statement is **incorrect**.

3. **Evaluate the third statement:**
- **Statement:** Beriberi is caused due to deficiency of vitamin B10.
- **Analysis:** Beriberi is actually caused by a deficiency of vitamin B1 (thiamine), not B10. Therefore, this statement is **incorrect**.

4. **Evaluate the fourth statement:**
- **Statement:** Pellagra is caused due to deficiency of vitamin B6.
- **Analysis:** Pellagra is caused by a deficiency of niacin (vitamin B3), not vitamin B6 (pyridoxine). Therefore, this statement is **incorrect**.

### Conclusion:
Based on the evaluations:
- The correct statements are:
- Statement 1: Hypoprothrombinemia is caused due to deficiency of vitamin K (Correct).
- Statement 2: Dermatitis is caused due to deficiency of riboflavin (Incorrect).
- Statement 3: Beriberi is caused due to deficiency of vitamin B10 (Incorrect).
- Statement 4: Pellagra is caused due to deficiency of vitamin B6 (Incorrect).

Thus, the correct answer is **Statement 1 only**.
