Final answer:
The correct answer is A) Push rod, which is an engine component that transfers motion from the camshaft lifters to the valve rocker arms in an internal combustion engine.
Step-by-step explanation:
The correct answer to the question: "A(blank) rod transmits motion from the lifters to the valve rocker arms." is A) Push rod. A push rod is an engine component in a vehicle's internal combustion engine. It is used to transfer motion from the camshaft lifters directly to the rocker arms, which in turn operate the engine's valves.
The push rod enables the engine to function efficiently by ensuring that the valves open and close at the correct times during the combustion cycle. This is fundamental to engine performance as it directly affects the air/fuel mixture intake and exhaust gas expulsion.
