Zinc plates commonly found in refrigeration systems and used as sacrificial anodes are located where?

AI Explanation
The correct answer is D) salt water side of the condenser. Zinc plates are commonly used as sacrificial anodes in refrigeration systems to protect the condenser from corrosion caused by the salt water side of the system. The zinc plates are located on the salt water side of the condenser, where they corrode instead of the condenser, preventing damage to the condenser. The other options are incorrect because: A) the cooling water suction strainer is not in contact with salt water, B) the refrigerant side of the condenser does not require sacrificial anodes, and C) the evaporator coils are also not in contact with salt water.
