The correct answer is: 0
Given that, a circuit containing 5 resistances with a battery as shown in figure.



Rearranging the circuit, we get a balanced Wheatstone bridge


As $\frac{R_1}{R_2}=\frac{R_3}{R_4}=\frac{2}{5}$
$\therefore$ No current will pass through the inductor coil i.e., $I=0$
Now, energy stored in inductor is
$$
U=\frac{1}{2} L I^2
$$
Hence, $U=0$
