Capacitors and inductors store energy.

Capacitors and inductors store energy by building up electric and magnetic fields, respectively. A capacitor holds energy in the electric field between its plates, with energy proportional to (1/2) C V^2. An inductor stores energy in the magnetic field around its coil, with energy proportional to (1/2) L I^2. They are not energy sources; they don’t generate energy, they simply store and release it as voltage and current change. They can store energy in both DC and AC circuits, not just DC. So the statement that they store energy is correct. The other options fail because these components do not generate energy, they can store energy in non-DC situations, and they are not limited to DC circuits.
