Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Paraxial rays are the rays that are close to the principal axis of a lens or mirror and make a very small angle with the axis. By definition, the angle between paraxial rays and the principal axis is considered to be 0◦.
Thus, the correct answer is 0◦.
