Which vessel, if navigating independently in ice, is more likely to become beset due to inadequate horsepower?

Correct Answer: Option D — A 630 ft. bulk ore carrier with 3500 H.P.

A massive 630-foot bulk ore carrier powered by only 3500 horsepower possesses an extremely low power-to-displacement ratio and high frictional resistance. This severe deficit in propulsion thrust relative to hull size makes it highly susceptible to becoming beset in ice compared to shorter vessels.
