A ray of light incident at the optical centre of lens, passes undeviated after refraction.

Solution
The correct option is A True
Answer is A.
A ray of light passing through the optical center suffers no refraction, that is, it passes undeviated. This is because, when it passes through the optical center, it is perpendicular to the curved surface of the lens. Hence, the angle of incidence is zero and therefore the angle of refraction is also zero.
Hence, the statement is true.
