B. Gravitational force
C. Electrostatic force
D. Muscular force

Answer

To answer the question of which force is responsible for raising our body hair when we try to take off a terylene or polyester shirt in dry weather, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Scenario**: When we take off a terylene or polyester shirt, especially in dry weather, we often notice that our body hair stands up. This phenomenon occurs due to a specific type of force.

2. **Identifying the Type of Force**: The force responsible for this effect is related to electric charges. When we wear synthetic materials like terylene or polyester, they can become electrically charged due to friction with our skin.

3. **Electrostatic Charges**: The friction between the shirt and our skin can cause the shirt to gain a positive charge while our body may develop a negative charge, or vice versa. Opposite charges attract each other.

4. **Electrostatic Force**: The force that acts between charged objects is known as the electrostatic force. This force can cause our body hair to be attracted towards the charged shirt.

5. **Conclusion**: Therefore, the force responsible for raising our body hair when we take off a terylene or polyester shirt in dry weather is the **electrostatic force**.

### Final Answer:
The force responsible for raising our body hair when we try to take off a terylene or polyester shirt in dry weather is the **electrostatic force**.
