Solution

The correct option is D $W_{2} = W_{B} + B$
Consider the problem
$W_{1} = t r u e w e i g h t - b u o y a n t f o r c e = W_{A} - B$

Reading of the weighing scale
$\begin{matrix} W_{2} = h e i g h t o f w a t e r + b e a + r e a c t i o n t o b u o y a n t f o r c e \Rightarrow W_{2} = W_{B} + B \end{matrix}$

Hence, Option $D$ is the correct answer.
