Final answer:
Releasing the clutch lever too quickly often results in the engine stalling, as it disrupts the smooth power transfer to the drive wheels.
Step-by-step explanation:
If you release the clutch lever too quickly, the engine is likely to stall. This occurs because releasing the clutch too rapidly does not give the engine enough time to transfer the power smoothly to the drive wheels, causing an abrupt disruption in power flow that can stop the engine. This is quite the opposite of smooth acceleration, improved fuel efficiency, or enhanced braking.
Stalling a vehicle can happen if the clutch is not engaged smoothly, particularly in manual transmission cars. It’s important to release the clutch slowly and engage it with the accelerator in a balanced manner for a smooth driving experience.
The correct answer to the question is therefore: b. Engine stalls.
