• A. Starter Relay
• B. Starter Solenoid
• C. Battery Cable
• D. Ignition Switch

Answer: (B)

When starting a car, a heavy-duty switching device handles the high current from the battery to the starter motor. The starter solenoid is that device: energizing its coil closes its heavy-duty contacts and routes the battery’s high current straight to the starter, causing it to crank the engine. The ignition switch only sends a small control signal to energize the solenoid, not the full current. A starter relay may exist to activate the solenoid, but it doesn’t carry the main current to the motor. The battery cable is just the conductor, not the switch that delivers the current. So the component that delivers the high current to the starter motor is the starter solenoid.
