D. Marasmus,Kwashiorkor

Answer

To solve the question regarding the diseases X and Y in infants, we need to identify each disease based on the nutritional deficiencies described.

### Step-by-Step Solution:

1. **Identify the Nutritional Deficiencies**:
- Disease X is caused by a deficiency of both protein and calories.
- Disease Y is caused by a deficiency of protein but does not involve calorie deficiency.

2. **Understand the Diseases**:
- The disease caused by a deficiency of both protein and calories is known as **Marasmus**. This condition typically occurs in infants and is characterized by severe weight loss and muscle wasting.
- The disease caused by a deficiency of protein alone, while calories are sufficient, is known as **Kwashiorkor**. This condition is characterized by symptoms such as edema (swelling), a distended abdomen, and growth failure.

3. **Conclude the Answers**:
- Therefore, we can conclude that:
- Disease X (deficiency of protein and calories) is **Marasmus**.
- Disease Y (deficiency of protein without calorie deficiency) is **Kwashiorkor**.

4. **Final Answer**:
- Thus, X and Y are respectively **Marasmus and Kwashiorkor**.
