AI Explanation

The correct answer is C) high-pressure water wash. Explanation: A high-pressure water wash is an acceptable method for cleaning a dirty condenser coil in an air-cooled container refrigeration system. This method effectively removes dirt, debris, and other contaminants from the coil surfaces without causing damage. Using a weak acid solvent (option A) or a copper wire rotary brush (option B) could potentially damage the coil and is not recommended. The high-pressure water wash is a safe and effective cleaning method that aligns with industry best practices and regulatory requirements for maintaining air-cooled refrigeration systems on vessels. It is the most appropriate choice among the given options.
