A car moving with a velocity v1 overtake...

A car moving with a velocity `v_1` overtakes a person moving with a velocity `v_2` . The ratio of frequencies of sound Just before and after overtaking, is:

A

`(c-v_(1))(c-v_(2))/((c+v_(1))(c+v_(2))`

B

`((c+v_(2))(c-v_(2)))/((c-v_(1))(c+v_(1)))`

C

`((c+v_(1))(c+v_(2)))/((c-v_(1))(c-v_(1)))`

D

`((c-v_(1))(c+v_(2)))/(c+v_(1))(c-v_(2))`
