A sinker of weight `w_0` has an apparent weight `w_1` when weighed in a liquid at a temperature `t_1 and w_2` when weight in the same liquid at temperature `t_2`. The coefficient of cubical expansion of the material of sinker is `beta`. What is the coefficient of volume expansion of the liquid.

A

`(W_(0)-W_(1))/((W_(0)-W_(2))(t_(2)-t_(1)))+(beta(W_(0)-W_(1)))/(W_(0)-W_(2))`

B

`(W_(2)-W_(0))/(t_(2)-t_(1)) beta`

C

`(W_(1)-W_(0))/(t_(2)-t_(1)) beta`

D

`(W_(0))/((t_(2)-t_(1)))beta+(W_(2)-W_(1))/((W_(0)-W))beta`
