D. for building muscels

Explanation

### Step-by-Step Solution:

1. **Understanding Carbohydrates**: Carbohydrates are organic compounds made up of carbon, hydrogen, and oxygen. They are one of the main macronutrients that provide energy to the body.

2. **Main Function of Carbohydrates**: The primary role of carbohydrates in the body is to serve as a source of energy. When consumed, carbohydrates are broken down into glucose, which is used by the body for energy.

3. **Energy Supply**: Glucose is crucial for cellular respiration, which is the process by which cells produce ATP (adenosine triphosphate), the energy currency of the cell. This energy is essential for various bodily functions, including movement, growth, and repair.

4. **Nervous System Support**: Carbohydrates also play a vital role in providing energy to the nervous system. The brain relies heavily on glucose as its primary energy source. Without adequate carbohydrate intake, cognitive functions may be impaired.

5. **Muscle Development**: While carbohydrates are not directly responsible for building muscle, they are important for recovery and performance during exercise. Adequate carbohydrate intake helps replenish glycogen stores in muscles, which is essential for muscle development and endurance.

6. **Conclusion**: In summary, carbohydrates are mainly used by the body to provide energy and support the nervous system.
