What causes current to alternate in ac circuit

A capacitor with plates separated by distance d is charged to a potential difference ΔVC. All wires and batteries are disconnected, then the two plates are pulled apart (with insulated handles) to a new separation of distance 2d.

Which method of separation can be used for a heterogeneous mixture? A. by distillation B. by densities C. by chromatography D. by acidification
