Select the correct option:

A

$\tan ^{-1}\left[\frac{q}{m g} \times \frac{C_1\left(V_2-V_1\right)}{\left(C_1+C_2\right)(d-t)}\right]$

B

$\tan ^{-1}\left[\frac{q}{m g} \times \frac{C_2\left(V_2-V_1\right)}{\left(C_1+C_2\right)(d-t)}\right]$

C

$\tan ^{-1}\left[\frac{q}{m g} \times \frac{C_2\left(V_1+V_2\right)}{\left(C_1+C_2\right)(d-t)}\right]$

D

$\tan ^{-1}\left[\frac{q}{m g} \times \frac{C_1\left(V_1+V_2\right)}{\left(C_1+C_2\right)(d-t)}\right]$
