An AC electric motor has two main parts. Which pair correctly identifies them?

Explanation:
AC electric motors operate with two key components: a stationary part that houses the windings (the stator) and a rotating part inside that turns the shaft (the rotor). The stator creates a magnetic field when fed with AC, and this rotating magnetic field pushes the rotor to spin, producing mechanical motion. This pairing—stator plus rotor—is what defines an AC motor. Options like armature and brushes belong to DC machines, disconnect switches and fuses are protective devices, and slip rings are a rotor feature used in specific designs but not the fundamental two-part structure.
