Assertion (A): A convex lens made up of glass can never form a virtual, erect, and diminished image.

Reason (R): Convex lens can give only a virtual enlarged image when an object is placed between the focus and pole of the mirror.

(1) Both Assertion and Reason are true and the reason is the correct explanation of the assertion.

(2) Both Assertion and Reason are true but the reason is not the correct explanation of the assertion.

(3) Assertion is a true statement but Reason is false.

(4) Both Assertion and Reason are false statements.
