Which statement about the Mark VIII SDV is true?

Explanation:
Electric propulsion is essential for an SDV to operate fully submerged. Diesel engines need air and produce exhaust, which isn’t possible or safe while underwater, so electric motors powered by batteries are used for submerged travel. The Mark VIII SDV was designed as a compact, battery-powered craft to carry a six-person crew: two pilots to maneuver and four divers to perform the mission. This setup fits the vehicle’s size and purpose, whereas a diesel version couldn’t operate submerged and a larger crew would go beyond its intended capacity.
