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))`
