Answer 2

Both P and Q are incorrect. (Option B)

• Any beam that crosses through the optical center will be unaltered. The optical center is the lens's center.
• A ray goes through focus when it is passed from the primary axis.
• A ray goes parallel to the major axis as it passes through the focus of the lens.
• The beam that passes through the center of curvature is the only one that is not deflected.
• Thus, both P and Q are incorrect.
