• D. Glass ware

Answer 1

The correct option is C Polythene bags and plastics

As a result of various activities of mankind, our environment is getting increasingly polluted. pollutants are of 2 types: Biodegradable and non-bio degradable

Biodegradable pollutants are the ones which decompose after some time but non-bio degradable pollutants are the ones which don't degrade easily.

Plastics are non-bio degradable wastes. They remain intact until a long period of time. it takes thousands of years for plastic to get rid of its toxic substances and break down. Thus, their toxic chemicals cause harm to the plants. Apart from this, if any plastic material or polythene bag is eaten by animals, they eat the toxic substance present in them and thus catch deadly diseases.

Thus, Plastics and polythene bags are extremely harmful to the environment.

So, option C ' Polythene bags and plastics' is the correct option.
