Correct answer: B
$$\begin{aligned} \& \text { Given, } l=2 \mathrm{~A} \text { and } \frac{d i}{d t}=+1 \mathrm{~A} / \mathrm{s}\\ \& \begin{aligned} \& V_A-L \frac{d i}{d t}-5-i \times 2=V_B \\ \& \Rightarrow V_A-1 \times 1-5-2 \times 2=V_B \\ \& \Rightarrow V_A-V_B=10 \text { volt } \end{aligned} \end{aligned}$$
