Since no charge will flow in steady state so

$V_{A} - V_{C} = \frac{q _{1}}{5} + \frac{q _{2}}{5} \Rightarrow - 20 = \frac{q _{1} + q _{2}}{5} \Rightarrow q_{1} + q_{2} = - 100 μ C \dots\dots\dots .. (1)$

$V_{B} = \frac{- q _{3}}{5} + \frac{q _{1} - q _{2} - q _{3}}{5} \dots\dots\dots .. (2)$

$V_{0} = \frac{q _{1} - q _{2} - q _{3}}{5} \dots\dots\dots .. (3)$

If charge $q_{2}$ is given the $q_{1}$ will be calculated from equation (1) $- 10 = \frac{q _{1}}{5} + \frac{q _{4}}{5} \Rightarrow q_{4}$ can be calculated so $V_{0}$ can be calculated If $q_{4}$ is known $q_{3}$ can be calculated so $V_{B}$ can be calculated Hence (B) and (D) can be true
