Correct answer
C
Step-by-step explanation
In magnitude form, $\begin{aligned} & \left|\operatorname{Emf}_{\text {ind }}\right|=\left|(-) L \frac{\mathrm{di}}{\mathrm{dt}}\right| \\ & \Rightarrow 0.1=\frac{(\mathrm{L})[+2-(-2)]}{0.2} \\ & \Rightarrow \mathrm{L}=\frac{0.1 \times 0.2}{4}=5 \mathrm{mH} \end{aligned}$
