answer :- option (B)
we know, when a ray of light passes through the centre of curvature of the concave mirror, it is incident on mirror at 90° . hence, the incident ray concides with the normal and retraces its path.
e.g., reflected ray by concave mirror will pass through centre of curvature.
hence, option (B) is correct.

Light passing through centre of curvature will retrace its path.
As light falling asleep by passing through center of curvature woll appears to fall on mirror perpendicularly.
