In the figure shown, an observer `O_1` floats (static) on water surface with ears in air while another observer `O_2` is moving upwards with constant velocity `V_1=(V)/(5)` in water. The source moves down with constant velocity `V_S=(V)/(5)` and emits sound of freqeuncy `f`. The velocity of sound in air is `V` and that in water is `4V`. For the situation shown in figure.

A

The wave length of the sound received by `O_(1)` is 4v/5f

B

The wave length of the sound received by `O_(1)` is v/f

C

The frequency of the sound received by `O_(2)` is 2 if/ 16

D

The wavelength of the sound received by is `(4v)/(7f)`
