Question

1. the parking brake a. cannot operate if the car is moving. b. is usually set by pushing a pedal. c. must be released before starting the engine. d. can be safely used to stop the car.

Explanation:

The parking brake is designed to keep a stationary car in place. Operating it while the car is moving can be dangerous and may not function properly. It is usually set by pulling a lever or pushing a button, not always a pedal. It doesn't have to be released before starting the engine, but should be released before driving. And it's not designed to safely stop a moving car as it's not as effective as the regular brakes.

Answer:

A. cannot operate if the car is moving.
