    The answer is A.

    Explanation:

    It is a special case for a light ray to be incident on a reflective surface along the normal, the ray will be reflected right back to the normal. So the answer is A. The incident ray retraces its original path.

    a light ray is incident on a reflective surface along the normal

    so the angle of incident = angle bet. ray n the normal = 0

    n angle of incident = angle of reflection

    so angle of reflection = 0

    ans is A. The incident ray retraces its original path.
