Which one of the following is an energy giving component?

Options

A. Protein
B. Carbohydrates and fats
C. Roughage
D. Vitamins and minerals

Answer

To determine which one of the following is an energy-giving component, let's analyze each option provided:

1. **Protein**:
- Proteins are essential for body growth and tissue repair. They are often referred to as body-building foods because they help in building and repairing tissues. However, they are not primarily considered energy-giving components.

2. **Carbohydrates and Fats**:
- Carbohydrates are the main source of energy for the body. They are made up of carbon, hydrogen, and oxygen. Fats also serve as a significant source of energy. Together, carbohydrates and fats are classified as energy-giving components because they provide the necessary energy for bodily functions and activities.

3. **Vitamins and Minerals**:
- These are essential nutrients that support various bodily functions, but they do not provide energy. They are involved in metabolic processes and maintaining health but are not energy sources themselves.

4. **Roughage**:
- Roughage, or dietary fiber, aids in digestion and helps prevent constipation. While it is important for digestive health, it does not provide energy.

Based on this analysis, the correct answer to the question is **Carbohydrates and Fats**, as they are the energy-giving components.

### Step-by-Step Solution:
1. **Identify the components listed**: Protein, carbohydrates and fats, vitamins and minerals, roughage.
2. **Analyze each component**:
- **Protein**: Body-building food, not primarily an energy source.
- **Carbohydrates and Fats**: Main sources of energy for the body.
- **Vitamins and Minerals**: Essential for health but do not provide energy.
- **Roughage**: Aids digestion, does not provide energy.
3. **Determine the energy-giving component**: Conclude that carbohydrates and fats are the energy-giving components.
