Solution

The correct option is D
Doesn’t intersect at all

The ray parallel to the principal axis when hits the lens passes through the focus. Applying the law of reversibility, the ray passing through the focus, when it hits the lens becomes a ray parallel to the principal axis, which doesn’t intersect at all.
