Assertion (A)Low density polythene is used in the insulation of electricity carrying wires.
Reason(R )LDP is chemically inert.

Options

A. Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion
B. Both Assertion and Reason are correct but Reason is not the correct explanation of Assertion
C. Assertion is correct but Reason is incorrect
D. Assertion is incorrect and Reason is correct

Answer

To solve the question, we will analyze both the assertion and the reason provided, and determine their validity and relationship.

### Step 1: Analyze the Assertion
The assertion states, "Low density polythene is used in the insulation of electricity carrying wires."

- **Explanation**: Low-density polythene (LDP) is indeed used for insulating electrical wires. This is because it has good insulating properties, preventing the flow of electricity and protecting the wires from environmental factors.

### Step 2: Analyze the Reason
The reason states, "LDP is chemically inert."

- **Explanation**: Low-density polythene is chemically inert, meaning it does not easily react with other chemicals. This property contributes to its effectiveness as an insulator, as it does not degrade or react with moisture or other substances that might be present in the environment.

### Step 3: Determine the Relationship
Now, we need to determine if the reason provided is the correct explanation for the assertion.

- **Analysis**: While both the assertion and reason are correct, the reason does not explain why LDP is used for insulation. The primary reason LDP is used for insulation is that it is a poor conductor of electricity, not solely because it is chemically inert.

### Conclusion
Thus, we conclude that:
- Both the assertion and reason are correct.
- However, the reason is not the correct explanation for the assertion.

### Final Answer
The correct option is that both the assertion and reason are correct, but the reason is not the correct explanation for the assertion.
