Direct port wet systems have the simplest design.

• A. True
• B. Not sure
• C. It depends
• D. False

Answer: (D)

Direct port wet systems distribute water to each port individually, which usually means more piping runs, more joints, and possibly more valves to manage. That increased hardware and routing adds design complexity, so it isn’t the simplest configuration. A trunk-and-branch or centralized distribution approach typically offers a cleaner, fewer-parts layout with fewer potential failure points, making it simpler overall.
