✓
C

D

ANSWER · B
Engine braking is the safest method. It has three notable advantages: first, the differential evenly distributes braking torque to the left and right wheels, reducing skidding and fishtailing; second, it reduces the frequency of foot braking, preventing brake pad overheating that can weaken or eliminate braking force; third, vehicle speed stays within a controlled range, helping you slow down or stop in time for safety.
