Final Answer:
The parking brake applies and releases when you use the parking brake control. Option C is the answer.
Step-by-step explanation:
The parking brake, also known as the handbrake or emergency brake, is a separate braking system designed to keep a stationary vehicle in place. It is typically engaged using a lever or pedal, referred to as the parking brake control. Contrary to the vehicle's primary braking system, the parking brake is manually applied and released by the driver. Option 3 accurately describes the process; the parking brake engages when the control is operated, and it is released when the control is disengaged.
While the primary purpose of the parking brake is to secure a parked vehicle, it can also serve as an additional safety measure in emergency situations, providing a secondary means of braking.
Option C is the answer.
