A motor that is designed to start with a capacitor and run with a capacitor is specifically termed a capacitor-start, capacitor-run motor. This type of motor is engineered to use capacitors both in the starting phase and during the running phase to enhance performance. The starting capacitor provides additional torque to help the motor overcome inertia when it starts up, while the running capacitor improves efficiency and power factor during operation. This dual-use of capacitors allows the motor to perform better, especially in applications with variable loads.

In contrast, a split-phase motor is characterized by a simpler design that typically only utilizes a start winding and a run winding without capacitors, leading to less efficiency in starting and running. A capacitor-start motor, while also improving starting torque, usually does not employ a running capacitor for continuous operation. Induction motors do not rely on capacitors for starting or running, making them less suited for applications requiring high starting torque or efficiency.

The terminology and design specifics highlight the capabilities of the capacitor-start, capacitor-run motor, making it the correct answer for this question.
