    Statement $-1$ : Due to the motion of listener, the frequency of the sound waves (as received by listener) emitted by stationary source is affected.

    Statement $-2$ : Due to the motion of source, wavelength of the sound waves (emitted by source) as received by stationary listener is affected.

    Statement $-3$ : If receiver and source both are moving, the observed frequency must be different from the original frequency of source.

    Treat motion of source or listener as always along a line joining them for all above cases.
