What is the relation between reactance, resistance and impedance?

(a) Z=R+jX

(b) Z=R+X

(c) Z=R-X

(d) Z=R-jX

I got this question in an interview.

My doubt stems from Current and Voltage in a Capacitive Circuit topic in division Single Phase Series Circuits of Basic Electrical Engineering

Best answer
Correct choice is (a) Z=R+jX

The best explanation: The combination of resistance and reactance is known as impedance.                                                                              Z=R+jX

Where Z is impedance, R is resistance and X is reactance.
