Dielectric loss is more significant in AC applications, leading to reduced energy storage efficiency compared to DC.
Dielectric loss has no effect on energy storage in either AC or DC applications.
AC applications enhance dielectric loss, resulting in improved energy storage capabilities.
DC applications experience higher dielectric loss, thereby causing capacitors to store more energy.
Understanding the Answer
Let's break down why this is correct
Dielectric loss happens when the material’s dipoles cannot follow the changing electric field. Other options are incorrect because Many think loss is irrelevant, but in AC the energy that goes into heat is counted as loss; It’s easy to imagine that more loss means more storage, but loss is the opposite: it is the energy that disappears, not that it stays stored.

Definition
Capacitors store energy as electric field potential between conductors. Discharging a charged capacitor eliminates its stored energy. Observing no spark when shorting discharged capacitor plates demonstrates energy dissipation and charge flow principles.
