Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
Magnetic field lines exist in closed loops only.
A convex mirror would always produce an erect image, and a concave mirror may produce inverted or an erect image depending on the position of the object placed.
Thus, independent of the sign convention, the magnification of a convex mirror is always positive, but that of a concave mirror may be both positive or negative.
Hence, both statements are correct but reason is not correct explanation of assertion.
