Correct Answer:
Option A. Blackwater
Blackwater is the term used for untreated sewage that is released from the toilets. It contains pathogens and can contaminate greywater. Greywater is the water from sources other than toilets for example showering and kitchen. These two types of water are kept separate so that the processing and filtration of greywater can be done relatively easily.
