Answer

Brief Explanations:

An engine cut - off switch lanyard is attached to the operator. If the operator falls overboard, it pulls the switch, cutting off the engine and stopping the propeller, thus preventing a propeller strike. A safety harness keeps the operator attached to the vessel but doesn't stop the propeller. A loud whistle is for signaling and not for stopping the propeller. A bulletproof PFD is for flotation and not related to stopping the propeller.

Answer:

D. an engine cut - off switch lanyard
