Correct answer: Use the front and rear brakes at the same time.
Answer options
AUse the front and rear brakes at the same time. Correct
BUse only the rear brake and leave the front alone.
CUse only the front brake and leave the rear alone.
Why
Applying the front lever and the rear pedal together gives the shortest, most controlled stop. The front brake supplies most of the stopping power, while the rear adds stability, so relying on just one of them wastes braking ability.
