Answer:

1.C
The ability to conduct electricity is conductance. The capacitors do not distort electric field. The capacitors stores energy in form of electric field.
Capacitor is a charge storing device. The capacitance is the is the measure of amount of charge stored.

2.C
Increase the distance of separation between the parallel plate capacitor.
