The impedance value of a pure capacitor is?

(a) ωC

(b) 1/ ωC

(c) ωL

(d) R

This question was posed to me in a national level competition.

This interesting question is from Phase Relation in a Pure Resistor in section Introduction to Alternating Currents and Voltages of Network Theory

The correct choice is (b) 1/ ωC

For explanation: The impedance value of a pure capacitor is 1/ ωC. And the impedance of the capacitor is called capacitive reactance.
