Which of the following statements is true concerning the operating characteristics of a basic squirrel-cage induction motor?

Correct Answer: Option D — Rotor slip is dependent upon the motor load.

Slip is the difference between synchronous speed and rotor speed. As mechanical load increases, the rotor slows down, increasing the relative speed between the stator field and rotor bars. This induces more current, creating higher torque to meet the load demand, directly linking slip percentage to the applied motor load.
