(D) None of the above

Answer 1

Hint: Wastes are discarded or left over solid materials produced due to human activities. These waste refer to everything that goes out in the trash. The terms rubbish and trash are often used interchangeably for these solid waste materials.

Complete answer:
The various sources of solid wastes are municipal wastes, industrial wastes, hospital wastes, hazardous wastes, and electronic wastes (e-wastes). These solid wastes are responsible for landscape pollution.
industrial waste is defined as the waste that originates from different industries during the manufacturing of products such as paper industries.
Now let us match this with given options:-
(А) Factories and mills : industrial waste includes waste generated during manufacturing of substances in industries. The waste generated from different factories such as paper factory, textile industries acts as waste and that produced from mills such as sugar mills also constitute industrial waste.
(B) Dairy : during the production of dairy products the waste generated is used to manufacture different things, that is when butter is produced the waste generated can be used to make paneer or cheese so it does not consist of industrial waste.
(C) Sea : it is a water body. Water bodies do not produce waste on their own. It is due to human activities that waste is generated inside the sea. It includes the dead parts of aquatic plants and some aquatic animals but it does not constitute industrial waste.

Our required option is A. factories and mills.

Note:
There are many other types of waste also that constitutes industrial waste is municipal waste . Municipal solid wastes includes the wastes that are generated from homes, offices, stores, schools, hospitals etc., this type of waste materials are collected and disposed of by the municipality. The municipal solid wastes generally comprise paper, food wastes, plastic glass, metals, rubber, leather, textile, etc. We are increasing the use of non-biodegradable products. Any readymade packet of any good quality eatable, like biscuit packet contains a number of protective layers including one layer of plastic also. In cities, fruits and vegetables can be bought packed in beautiful polystyrene and plastic packaging contribute heavily to environmental pollution.
