Options

A. Statement-1 is true, statement-2 is true and statement2 is correct explanation for statement-5
B. Statement-1 is true, statement-2 is true and statement - 2 is NOT the correct explanation for statement-5
C. Statement - 1 is true, statement - 2 is false
D. Statement - 1 is false, statement - 2 is true.

Answer

To analyze the given statements and determine their validity, we can follow these steps:

### Step 1: Understand the Statements
- **Statement I**: `CuSO4` solution cannot safely be kept in a Zn vessel.
- **Statement II**: The position of Zn is lower than Cu in the electrochemical series.

### Step 2: Analyze Statement I
- **Explanation**: The statement claims that copper sulfate solution cannot be stored in a zinc vessel. This is based on the reactivity of the metals involved. Zinc is more reactive than copper.
- **Conclusion**: If zinc is placed in a copper sulfate solution, it will react and displace copper from the solution, leading to the formation of zinc sulfate and copper metal. Therefore, this statement is **true**.

### Step 3: Analyze Statement II
- **Explanation**: This statement asserts that zinc is positioned lower than copper in the electrochemical series. The electrochemical series ranks metals based on their reactivity.
- **Conclusion**: In the electrochemical series, zinc is actually above copper, indicating that zinc is more reactive than copper. Therefore, this statement is **false**.

### Step 4: Final Evaluation
- Based on the analysis:
- Statement I is **true**.
- Statement II is **false**.

### Step 5: Answer the Question
- The correct conclusion is that Statement I is true and Statement II is false.

### Summary:
- **Statement I**: True
- **Statement II**: False
