Answer»

The correct choice is (a) Suspended SOLIDS

For EXPLANATION I would SAY: The definition of Turbidity is the cloudiness or haziness of a fluid caused by suspended solids that are usually invisible to the naked eye. The measurement of Turbidity is an important test when trying to DETERMINE the quality of water. It is an aggregate optical property of the water and does not identify INDIVIDUAL substances; it just says something is there.
