Which of the following is a unit of inductive reactance?

Explanation:
Inductive reactance is a resistance-like opposition to current in an inductor that depends on frequency. Its value is X_L = ωL (or 2πfL). Since resistance is measured in ohms, X_L is expressed in ohms. The inductance L uses the unit henry, and angular frequency ω uses radians per second; because radians are dimensionless, (rad/s) × (H) simplifies to ohms (Ω). Volts and amperes, meanwhile, measure voltage and current, not opposition, and Henry is the unit of inductance, not reactance. So the unit for inductive reactance is ohms.
