(b) Homes
(c) Industries

Answer 1

The answer is option (a).

Sewers are not considered as a source of wastewater. Homes, industries and hospitals are considered as sources of wastewater. Sewers are a network of big and small pipes that carries sewage from the point where it is produced to the point of disposal, i.e. wastewater treatment plant. This network of big and small pipes forms a transport system called sewerage.
