Inductive reactance is best described as:

Inductive reactance is best described as the opposition that an inductor presents to alternating current (AC) flow. This phenomenon arises because an inductor, when subjected to AC, generates a magnetic field that is in opposition to changes in current, thereby impeding the flow of electricity. The inductive reactance depends on the frequency of the AC signal and the inductance of the coil. It is measured in ohms and is a crucial concept in alternating current circuits, as it impacts how circuits respond to varying frequencies.

The other choices do not accurately capture the essence of inductive reactance. The first two options refer to the opposition to direct current (DC) flow, which is not relevant to inductive reactance, as this concept specifically deals with AC. The last option mentions energy stored in an electric field, which relates to capacitance rather than inductive behavior. Thus, the correct choice clearly delineates the role of inductors in AC circuits and their inherent properties related to reactance.
