Answer

To determine the common source of carbohydrates, fats, and proteins from the given options, we will analyze each option step by step.

### Step 1: Understand the Nutritional Components
- Carbohydrates, fats, and proteins are essential macronutrients that our body needs for energy, growth, and overall health.
- A balanced diet should include all three macronutrients in appropriate proportions.

### Step 2: Analyze Each Option
1. **Option 1: Rice**
- Rice is primarily composed of carbohydrates, specifically starch.
- It contains very little protein and fat.
- **Conclusion**: Rice is not a common source of all three macronutrients.

2. **Option 2: Milk**
- Milk contains carbohydrates (in the form of lactose), proteins (casein), and fats (both saturated and unsaturated).
- For example, in 100 grams of milk, there are approximately:
- 5 grams of carbohydrates,
- 3.4 grams of protein,
- 1 gram of fat.
- **Conclusion**: Milk is a common source of carbohydrates, fats, and proteins.

3. **Option 3: Eggs**
- Eggs are rich in protein (albumin in egg whites) and contain fats (mostly in the yolk).
- However, they have very low carbohydrate content.
- **Conclusion**: Eggs are not a common source of all three macronutrients.

4. **Option 4: Ghee**
- Ghee is primarily composed of fats.
- It contains negligible amounts of carbohydrates and proteins.
- **Conclusion**: Ghee is not a common source of all three macronutrients.

### Step 3: Final Conclusion
- After analyzing all options, we find that **milk** is the only food item that contains significant amounts of carbohydrates, fats, and proteins. Therefore, the correct answer is **Option 2: Milk**.
