Choose the correct statement.

Options

A. Specific heat capacity of a body in all its states is constant.
B. Specific heat capacity of a body is different in different states
C. Specific heat capacity is a characteristic property of a material and it is different for different materials.
D. Both (b) and (c)

Explanation

To solve the question regarding the specific heat capacity of a body in different states, we need to analyze the statements provided and determine which one is correct.

### Step-by-Step Solution:

1. **Understanding Specific Heat Capacity**:
- Specific heat capacity is defined as the amount of heat required to raise the temperature of 1 kg of a substance by 1 degree Celsius.
- It is a property that varies between different materials and their states.

2. **Analyzing the Statements**:
- **Statement A**: "Specific heat capacity of a body in all its states is constant."
- This statement is incorrect because specific heat capacity can change depending on the state of the material (solid, liquid, gas).

- **Statement B**: "Specific heat capacity of a body is different in different states."
- This statement is correct. For example, the specific heat capacity of water is different when it is in solid form (ice), liquid form (water), and gaseous form (steam).

- **Statement C**: "Specific heat capacity is the characteristic property of a material."
- This statement is also correct. Specific heat capacity is a characteristic property that helps in identifying materials based on how they respond to heat.

3. **Conclusion**:
- Since Statement B is correct and Statement C is also correct, the correct answer to the question is that both B and C are correct.

### Final Answer:
The correct statements are:
- B: Specific heat capacity of a body is different in different states.
- C: Specific heat capacity is the characteristic property of a material.
