Which of the following is the symbol for impedance?

Explanation:
Impedance is the total opposition to current in an AC circuit and is shown with the symbol Z. It combines resistance and reactance, and is expressed as Z = R + jX, where R is the resistance (the real part) and X is the reactance (the imaginary part). The other symbols correspond to different quantities: R is resistance, I is current, and V is voltage, so they do not denote impedance.
