On a small passenger vessel, electrical connections must be protected by enclosures.

• A. Protected By Enclosures
• B. Exposed To Moisture
• C. Made Within Enclosures
• D. Made Using Raw Conductors

Answer: (C)

The main idea is that electrical connections must be kept inside protective boundaries to prevent accidental contact and to shield them from moisture and damage. The best choice says the connections are “Made Within Enclosures,” which directly expresses that the junctions and terminations are placed inside a protected enclosure. This enforces safety by keeping live conductors covered and away from moisture, reducing shock risk and corrosion.

Why the other ideas don’t fit: making connections exposed to moisture or using raw conductors would create hazards, and saying the connections are simply "protected by enclosures" is less precise about the act of performing the connection inside the enclosure.
