Correct Answer: Option B — Valve "14" is the king solenoid, valve "28" is the chill box solenoid, and valve "36" is the freeze box solenoid.

Standard marine refrigeration blueprints designate valve 14 as the main king solenoid controlling liquid flow from the receiver, while valves 28 and 36 serve as individual box solenoids for the chill box and freeze box respectively.
