Question

explain why A Ray of light passing through the centre of curvature of concave mirror get reflected along the same path​

Answer 1

A ray of light paying through the center of curvature of concave mirror get reflected along the same path because it strikes the mirror along the normal i.e. it incidences on to the mirror at 90 degree.

Answer 2

The light falling on the centre of curvature is reflected back along the same path because the incident ray falls on the mirror along the normal to the reflecting surface.
