Assertion: Electrons move away from a low-potential region to a high-potential region. Reason: Electrons have negative charge.

1. If both assertion and reason are true and the reason is the correct explanation of the assertion.
2. If both assertion and reason are true but the reason is not the correct explanation of the assertion.
3. If assertion is true but reason is false.
4. If the assertion and reason both are false.

Correct answer: If both assertion and reason are true and the reason is the correct explanation of the assertion.

Solution

The assertion is true because a negative charge moves opposite to the electric field, which is from higher potential to lower potential. Since electrons are negatively charged, the reason correctly explains the assertion.
