Answer 1

Option C). The connecting rod is attached to the crank pin on a crankshaft, which is pivotal in the engine's conversion of motion.

Step-by-step explanation:

Crank pin: The portion of a crankshaft to which the connecting rod is attached. In an engine, the crank pin serves as a pivot point for the connecting rod and is crucial to the transformation of linear motion into rotational motion. In contrast to the options of a valve rod, eccentric, or crosshead, the term "crank pin" refers specifically to the location on the crankshaft where the connecting rod is attached, enabling internal combustion within the engine.
