Assertion - Speed of mechanical wave in the medium depends on the velocity of source, relative to an observer at rest.Reason - Speed of mechanical wave is independent of the elastic and other properties such as mass density of the medium.

The correct option is C Both Assertion and Reason are incorrectThe speed of a mechanical wave with respect to the observer at rest depends only on the elastic and other properties of medium. It is independent of the velocity of the wave source.
