Answer 1

Answer: (A)

Concave lens and convex mirror can produces erect, diminished and virtual image. Image formation by a concave lens:

$AB$ = object, $A^{\prime }{B}^{\prime }$= image
Image is erect, diminished and virtual.
Image formation by convex mirror:

$AB$ = object, $A^{\prime }{B}^{\prime }$ = image
Image is erect, diminished and virtual.
