Detailed Solution

A light ray passing through the optical centre point situated on the principal axis of a lens goes undeviated.
After being refracted by the lens, a light beam that was initially parallel to the primary axis travels through the focus. A light beam going through the convex lens' optical centre does not bend after refraction but instead travels straight. After refraction via the convex lens, a light beam that has passed through the focus becomes parallel to the principal axis.
