B Correct answer
Explanation

Reactance is the opposition to AC flow in a capacitor, known as capacitive reactance. Capacitors store and release energy in their electric field, creating opposition to changes in voltage. Capacitive reactance decreases as frequency increases. Admittance is the inverse of impedance, conductance is the inverse of resistance, and reluctance relates to magnetic circuits, not capacitors.
