Aright hand end of the floating lever will move up
Bspeeder rod will move down
Cpilot valve plunger will move down
Doil pressure under the power piston will increase
AI Explanation
The correct answer is A) the right-hand end of the floating lever will move up. As the load on the engine is decreased, the engine speed will increase. This causes the right-hand end of the floating lever to move upwards, which in turn causes the speeder rod to move downwards. This downward movement of the speeder rod reduces the amount of fuel delivered to the engine, bringing the engine speed back to the desired setting. The other answer choices are incorrect because: B) the speeder rod will move down (as explained above), C) the pilot valve plunger will not move down, and D) the oil pressure under the power piston will decrease, not increase, as the load on the engine is reduced.
