When riding a motorcycle, how can you achieve an engine braking effect?

In the photo you can see the engine and footrest of a cruiser-type motorcycle. You get the effect of engine braking by easing off the throttle without pulling the clutch lever - answer A.

Engine braking works like this: after the throttle is closed, the engine stops driving the wheel and instead creates resistance itself, because the pistons must suck air through the closed throttle and overcome friction; this resistance passes through the clutch and gearbox to the rear wheel and slows the motorcycle down. The condition is that the drive stays connected: when you pull in the clutch (answer B) or select neutral (answer C), you disconnect the engine from the wheel and the motorcycle rolls freely, only faster and faster on a descent. The lower the gear, the stronger the engine braking - that is why before a long descent you change down, and in town when approaching traffic lights you close the throttle earlier instead of riding on the clutch and brakes. The Road Traffic Act requires you to brake in a way that does not cause danger, and engine braking is smooth, does not lock the wheel and saves the brakes. Be careful with a sudden change down on a slippery surface: the rear wheel may slide.
