A3/8 inch
B1/2 inch
C5/8 inch
D3/4 inch
AI Explanation
The correct answer is C) 5/8 inch. The 5/8 inch pipe size is not as commonly used as the other listed options (3/8 inch, 1/2 inch, and 3/4 inch) for standard plumbing and piping applications on vessels. These other sizes are much more prevalent and widely available for marine use. The 5/8 inch size is less standardized and typically not stocked as extensively by suppliers of marine equipment and fittings.
