Solution

The correct options are
A Bad odour
C Small suspended solids
Aeration causes bacteria to consume small suspended organic solids by aerobic respiration. In the process, bad odour of the water is also removed. This occurs because the organic compounds which make up the odour and solids are broken down during aerobic respiration by the decomposers (the bacteria use them as food).
