B. Statement 1 is true statement 2 is true statement 2 is not a correct explanation for statement 1
C. Statement 1 is true statement 2 is false
D. Statement 1 is false statement 2 is true

Explanation

To analyze the given statements and determine their validity, we will break down the concepts of disproportionation reactions and the behavior of transition metals step by step.

### Step-by-Step Solution:

1. **Understanding Disproportionation Reactions**:
- A disproportionation reaction is a specific type of redox reaction where a single substance is both oxidized and reduced simultaneously. This means that one part of the substance loses electrons (is oxidized) while another part gains electrons (is reduced).

2. **Analyzing Statement 1**:
- The reaction provided is:
\[ 2 \text{CuCl} \rightarrow \text{CuCl}_2 + \text{Cu} \]
- In this reaction, copper (Cu) in CuCl has an oxidation state of +1. In CuCl2, the oxidation state of copper is +2, and in elemental copper (Cu), the oxidation state is 0.
- Here, Cu is being oxidized from +1 to +2 (losing an electron) and simultaneously, another Cu is being reduced from +1 to 0 (gaining an electron).
- Since one substance (copper) is undergoing both oxidation and reduction, this confirms that the reaction is indeed a disproportionation reaction.

3. **Analyzing Statement 2**:
- The statement claims that all transition metals exhibit disproportionation reactions.
- While many transition metals can undergo oxidation and reduction due to their variable oxidation states, not all transition metals participate in disproportionation reactions.
- Disproportionation reactions are specific to certain conditions and certain metals. Therefore, this statement is false.

4. **Conclusion**:
- Statement 1 is true: The reaction is a disproportionation reaction.
- Statement 2 is false: Not all transition metals show disproportionation reactions.

### Final Answer:
- Statement 1 is true, and Statement 2 is false. Therefore, the correct option is that Statement 1 is true and Statement 2 is false.
