A solid whose volume does not change with temperature, floats in a liquid. Fractions `f_(1)andf_(2)` of its volume remain submerged for two different temperatures `t_(1)andt_(2)` of liquid. The volume coefficient of expansion of liquid is

A

`( f_1 + f_2)/( f_1 t_1 + f_2 t_2)`

B

`( f_1 + f_2)/( f_2 t_1 + f_1 t_2)`

C

`( f_1 - f_2)/( f_1 t_1 + f_2 t_2)`

D

`( f_1 - f_2)/( f_2 t_1 - f_1 t_2)`
