For an incident ray directed towards center of curvature of a spherical mirror, the reflected ray:

  1. retraces it's path
  2. passes through the focus
  3. passes through the pole
  4. becomes parallel to the principal axis

Answer

retraces it's path

Reason — A line joining the centre of curvature to any point on the surface of mirror is normal to the mirror at that point, so a ray AD passing through the center of curvature C (or appearing to pass through through the centre of curvature C) is incident normally on the spherical mirror.
Since it's angle of incidence is zero, therefore the angle of reflection will also be zero and the ray AD gets reflected along it's own path DA as shown below.

For an incident ray directed towards center of curvature of a spherical mirror, the reflected ray (a) retraces its path (b) passes through the focus (c) passes through the pole (d) becomes parallel to the principal axis. Reflection of Light, Concise Physics Solutions ICSE Class 9.
