Options

(a)

Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).

(b)

Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).

(c)

Assertion (A) is true, but Reason (R) is false.

(d)

Assertion (A) is false, but Reason (R) is true.

Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).

Magnetic field lines

Imaginary lines

Direction of field

Magnetic field lines do not intersect each other because the tangent to the field lines at any point gives the direction of the field at that point. If two field lines intersect, it would mean that at the point of intersection, the compass needle would point towards two directions, which is not possible.
