The acceleration pump is a component that is used to provide a sudden burst of fuel during rapid engine acceleration. This ensures that enough fuel is delivered to the engine in order to maintain performance and prevent fuel starvation.

Option B, the engine-driven fuel pump, is incorrect because it is responsible for providing a constant supply of fuel to the engine, not a sudden burst during acceleration.

Option C, the power enrichment unit, is also incorrect because it is responsible for controlling the air and fuel mixture ratio, not directly providing fuel to the engine.

Option D, the fuel reservoir, is incorrect because it is simply a storage container for fuel and does not play a role in ensuring fuel delivery during acceleration.
