Which type of Marine Sanitation Device (MSD) is used solely for the storage of sewage and flush water at ambient air pressure and temperature?

AI Explanation
The correct answer is C) Type III. Type III MSDs are used solely for the storage of sewage and flush water at ambient air pressure and temperature. They do not treat or disinfect the sewage, but rather hold it in a holding tank until it can be properly disposed of. Type I and Type II MSDs actively treat the sewage, while Type IV MSDs use incinerators or other advanced technology to process the waste. Therefore, Type III is the only option that describes a simple storage system without any active treatment.
