ABarrel

CControl Rack

AI Explanation
The correct answer is A) Barrel. The barrel is the component labeled "N" in the illustration MO-0061 of the fuel injection pump. The barrel is the cylindrical housing that contains the plunger and controls the amount of fuel delivered to the engine cylinder. This is the key function of the barrel in a fuel injection pump system. The other options are incorrect because the sleeve is a different component, the control rack controls the movement of the plunger, and the plunger is a separate component from the barrel within the fuel injection pump.
