Aeration is done to remove unpleasant tastes and odour. So, according to option only (A) is right.

Also, activated carbon, ozone, etc can be used for aeration.

Odour is right according to Aghor book.

Colour. According to the Aghor book.

I think the answer is colour, odour and taste.

Right or not?

Aeration is the process of bringing water and air into close contact in order to remove dissolved gases, such as carbon dioxide, and to oxidize dissolved metals such as iron. It can also be used to remove volatile organic chemicals (VOC) in the water.

Aeration is often the first major process at the treatment plant. During aeration, constituents are removed or modified before they can interfere with the treatment processes.
