B. Iodine - Marasmus
C. Protein - Cheilosis
D. Vitamin D - Osteomalacia

Explanation

To solve the question of matching deficiency diseases with their related nutrients, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Deficiency Diseases and Nutrients**: We need to look at the options provided and identify the deficiency diseases and the nutrients associated with them.

2. **Evaluate Each Option**:
- **Option 1**: Vitamin A and Scurvy
- Scurvy is actually caused by a deficiency of Vitamin C, not Vitamin A. Therefore, this option is incorrect.
- **Option 2**: Iodine and Marasmus
- Marasmus is a condition caused by a severe deficiency of calories and protein, not specifically related to iodine. Thus, this option is also incorrect.
- **Option 3**: Cheilosis and Riboflavin
- Cheilosis (or angular cheilitis) is actually associated with a deficiency of riboflavin (Vitamin B2). However, the term "cheilosis" is often confused with other conditions, but riboflavin is indeed the correct nutrient. This option is correct.
- **Option 4**: Vitamin D and Osteomalacia
- Osteomalacia is a bone disease that occurs due to a deficiency of Vitamin D. This option is correct.

3. **Select the Correct Match**: After evaluating all the options, we find that:
- The correct matches are:
- Cheilosis (associated with Riboflavin)
- Osteomalacia (associated with Vitamin D)

4. **Final Decision**: Among the provided options, the most accurate match is that Vitamin D deficiency leads to Osteomalacia.

### Conclusion:
The correct match of the deficiency disease and related nutrient is:
- **Vitamin D deficiency is associated with Osteomalacia.**
