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, we need to analyze the statements provided regarding specific heat capacity and determine which ones are correct.

### Step-by-Step Solution:

1. **Understanding Specific Heat Capacity**:
- Specific heat capacity is defined as the amount of heat energy required to raise the temperature of a unit mass of a substance by 1 degree Celsius.
- It is a property that indicates how much heat a substance can store.

2. **Evaluating Statement A**:
- Statement A claims that the specific heat capacity of a body in all its states is constant.
- This statement is **incorrect** because the specific heat capacity can vary between different states of matter (solid, liquid, gas) for the same material.

3. **Evaluating Statement B**:
- Statement B states that the specific heat capacity of a body is different in different states.
- This statement is **correct**. For example, the specific heat capacity of water as a liquid is different from that of ice (solid) and steam (gas).

4. **Evaluating Statement C**:
- Statement C asserts that specific heat capacity is a characteristic property of a material and it is different for different materials.
- This statement is also **correct**. Different materials have different specific heat capacities. For instance, metals generally have lower specific heat capacities compared to water.

5. **Conclusion**:
- Based on the evaluations:
- Statement A is incorrect.
- Statements B and C are correct.
- Therefore, the correct answer is that both B and C are true.

### Final Answer:
The correct statements are B and C.
