Solution
(ii) and (iii) only
Explanation:
A magnifying glass uses a convex (converging) lens, so statement (i) “is a diverging lens” is false.
For a magnifying glass, the object is placed between the optical centre and the principal focus of the convex lens. In this position, the lens forms a virtual, erect and magnified image.
