Question 657 Deck General

The correct answer is B) Jib. The boom of a crane is commonly referred to as the jib. The jib is the horizontal, elevated arm of the crane that extends out from the crane's mast or tower and is used to lift and move loads. This terminology is standard in the crane industry and is also used in the US Coast Guard Captain's License Examinations. The other answer choices are not correct terms for the boom of a crane. A "rider" typically refers to an additional attachment or feature on a crane, "lift" is the action of raising a load, and "all of the above" is not a correct name for the crane's boom.
