Solution

The correct option is C I, II and III
There are some special rays which follow a fixed pattern on passing through a convex lens:

A ray of light parallel to the principal axis passes through the principal focus on the other side.

A ray passing through principal focus will emerge parallel to the principal axis.

A ray passing through the optical centre of a lens will emerge without any deviation.

Hence, image I, II, and III are the correct representations of the ray diagram.
