Solution

The correct option is B (A) - r, (B) - p, (C) - s, (D) - q
Change in apparent frequency due to relative motion between sources and listener is Doppler effect.
A - r
Intensity of sound varies with time in case of beats.
B - p
Sound waves in air are longitudinal in nature.
C - s
Light waves are transverse in nature.
D - q
