With regard to fresh water generators, what statement concerning brine is true?

Correct Answer: Option B — Brine is the unevaporated sea water of a fresh water generator as the result of distillation.

Brine is the concentrated, unevaporated seawater remaining in the evaporator after a portion of the feed has been converted to vapor. Because only pure water evaporates, the remaining solution becomes increasingly saline, requiring continuous discharge to prevent excessive salt concentration and subsequent scale buildup on heating surfaces.
