Correct answer

Release the accelerator with an appropriate gear engaged, braking when needed.

Anticipation lets you release the accelerator and slow down with an appropriate gear engaged, using the brakes when needed. Unnecessary shifts to very low gears or maximising engine-braking time are not required. In fuel-injected engines, fuel delivery may stop during overrun above idle speed. Never drive with the engine switched off.
