The current I in an inductance coil varies with time according to the graph shown. Which one of the following plots shows the variation of voltage in the coil with time?

The correct answer is Option (3)

for time interval $0<t_0<t/2$

$I=-Kt$, where $-k$ is slope.

and, for inductor -

$V=-L\frac{di}{dt}⇒v_1=+KL$

$⇒I_1=+Kt$, where K is slope.
