For a real image formed by a convex lens, the ratio of I : O = 2 : 5, then the object is :
(I is the height of the image and O is the height of the object)
- (a)between O and F
- (b)beyond 2F
- (c)at F
- (d)between F and 2F

beyond 2F
Reason — Here, real image size < object size and this happens when the object is placed beyond 2F.
