AI Explanation
The correct answer is B) Totally enclosed, fan-cooled. The motor labeled "A" in the illustration EL-0001 is required to have a totally enclosed, fan-cooled enclosure, as per the regulations for motor enclosures on commercial vessels. This type of enclosure provides protection from the elements while also allowing for active cooling of the motor, which is necessary for its safe and reliable operation on a marine vessel. The other options are incorrect because: A) Totally enclosed does not provide active cooling, C) Open, drip-proof does not provide sufficient protection from the marine environment, and D) Open is not an appropriate enclosure for a motor on a commercial vessel.
