Consider a source of sound `S`, and an observer `P`. The source emits sound of frequency `N_(0)`. The frequency observed by `P` is found to be `N_(1)` if P approaches S at a speed v and S is stationary; `N_(2)` if S approaches P at a speed v and P is stationary and `N_(3)` if each of P and S has speed v/2 towards one another ​

A

`n_1 = n_2 = n_3`

B

`n_1 lt n_2`

C

`n_3 gt n_0`

D

`n_3` lies between `n_1` and `n_2`
