The question Statement $I$ (Assertion) and Statement $II$ (Reason). The question has $4$ choices (a), (b), (c) and (d) out of which ONLY ONE is correct. So, select the correct choice.

Choices are

Statement $I$: Two magnetic field lines can't intersect each other.

Statement $II$: The magnetic field is having a unique direction at a particular location.

• A. Statement $I$ is True, Statement $II$ is True; Statement $II$ is a correct explanation for Statement $I$
• B. Statement $I$ is True, Statement $II$ is True; Statement $II$ is NOT a correct explanation for Statement $I$
• C. Statement $I$ is True, Statement $II$ is False
• D. Statement $I$ is False, Statement $II$ is True

Answer 1

The correct option is A

Statement $I$ is True, Statement $II$ is True; Statement $II$ is a correct explanation for Statement $I$

Explanation for Assertion statement:

1. Two magnetic field lines cannot intersect since this would result in two magnetic field directions at the intersection location, which is impossible.

Explanation for Reason statement:

1. At a certain point, the magnetic field has a unique direction.
2. So, the intersection of magnetic field lines does not make any sense.

Statement $I$ is True, Statement $II$ is True; Statement $II$ is a correct explanation for Statement $I$.

Hence, option (a) is correct.
