ABed plate
BColumn
CEntablature
DTie rod
AI Explanation
The correct answer is D) Tie rod. In a large, slow-speed, main propulsion diesel engine, the tie rods are under tension when the engine is running. Tie rods are the structural components that connect the cylinder head to the engine block, and they must withstand the high pressures and forces generated during the engine's operation. The other components listed, such as the bed plate, column, and entablature, are not directly under tension in the same way as the tie rods.
