Which of the following statements is true concerning the attached illustration? Illustration GS-RA-12 Illustration GS-RA-12: the U.S. Coast Guard has not released this illustration.

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 diagrams identify the main liquid line control as the king solenoid ("14"), while branch lines feeding medium-temperature chillers ("28") and low-temperature freezers ("36") operate independently based on respective box thermostats.
