Dunnage may be used to protect a cargo from loss or damage by __________.

Correct Answer: Option D — ship's sweat

Ship's sweat occurs when warm, moist air inside the hold contacts cold ship structures, causing condensation. Dunnage creates an air gap between the cargo and the ship's sides or deck, preventing direct contact with cold steel and allowing air circulation to mitigate moisture accumulation and subsequent water damage to the cargo.
