Question
Assertion :The apparent frequency which is the frequency as noted by an observer or an observing detection device of the acoustic wave that moves from the source to the observer propagating in a medium many be different from its true frequency. Reason: A source in motion relative to an observer sends out less or more number of waves per metre distance in the medium and an observer in motion collects less or more number of waves per second than when both of them remain at rest relatively.

Solution
The correct option is C Assertion is correct but Reason is incorrect
Option "C" is correct.
As the frequency of source doesn't change but apparent frequency changes according to the direction of motion of source and receiver
