Explanation:

In internal combustion engines, the connecting rod (spelled as "connectng rod" in the option) is the component that links the piston to the crankshaft, converting the piston's linear motion into the crankshaft's rotational motion. Valves control gas flow, the crankcase encloses the crankshaft, and the camshaft operates the valves, none of which connect the piston to the crankshaft.
