Explanation

Solution: The push rod is an essential component in an internal combustion engine, especially in overhead valve (OHV) engines . It plays a crucial role in the valve actuation mechanism . Function of Push Rod: - The push rod transmits motion from the tappet (or lifter) to the rocker arm . - It helps in opening and closing the engine valves by transferring the camshaft motion. - It ensures proper valve timing and smooth engine operation. Analysis of Options: - Option A: Valve and valve spring → Incorrect , as the push rod is not directly connected to the valve spring. - Option B: Valve and rocker ram → Incorrect , because the push rod is positioned between the tappet and rocker arm , not the valve. - Option C: Tappet and rocker ram → Correct , as the push rod connects the tappet (lifter) to the rocker arm . - Option D: None of these → Incorrect , as Option C provides the correct answer. Conclusion: The correct answer is Option C: Tappet and rocker ram , as the push rod transmits motion between these two components in an engine's valve mechanism.
