Question 102Motor Plants - 1st Asst/Chief

The correct answer is A) top. The device labeled "D" in the illustration MO-0112 is the bowl top. This is the correct answer based on the standard terminology used in the US Coast Guard Captain's License Examinations to describe the components of a marine engine. The bowl top, also known as the air intake housing or air cleaner cover, is the removable upper part of the air intake system that covers the air filter or air cleaner element. The other answer choices are incorrect because the "hood" (B) is not a standard term used to describe this component, the "hub" (C) refers to a different part of the engine, and the "cover" (D) is too generic and does not specifically identify the bowl top.
