A: Electrical power through transmission lines is transmitted at high voltage.
R: At high voltage theft of power is checked.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion.
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion.
C. If Assertion is true statement but Reason is false.
D. If both Assertion and Reason are false statements.

Answer

To solve the assertion and reason question, we need to analyze both statements and determine their validity and relationship.

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that electrical power through transmission lines is transmitted at high voltage.
- This is true because transmitting power at high voltage reduces the current in the transmission lines, which minimizes energy losses due to resistance.

2. **Understanding the Reason (R)**:
- The reason states that at high voltage, theft of power is checked.
- This is also true because higher voltage transmission can make it more difficult to tap into the lines without detection. Additionally, lower current reduces the risk of power theft, as the energy loss due to resistance is minimized.

3. **Analyzing the Relationship**:
- The assertion and reason are both true.
- The reason provides a correct explanation for the assertion. By transmitting power at high voltage, the current is reduced, which not only minimizes energy loss but also makes it more difficult for unauthorized users to steal power.

4. **Conclusion**:
- Both the assertion and reason are true, and the reason correctly explains the assertion. Therefore, the answer is that both statements are true, and the reason is the correct explanation of the assertion.

### Final Answer:
Both assertion (A) and reason (R) are true, and R is the correct explanation of A.
