D.None

Answer 1

Hint: The 4Rs are an easy way to remind us of how a difference can be made. Each phase offers a different way for us to think about what we use and how we dispose of waste. Each move has a strong emphasis on educating us. It allows us to define the modifications we can make.

Complete answer:
The concept of Waste Management is the 4R theory. That's very good as waste is recycled or burned correctly and eliminated from the communities properly. It removes conditions which are unhygienic.
Energy is obtained by burning waste to get thermal energy.
4R means Eliminate, Reuse, Recycle and Restore.
(i) Minimize: It is necessary to reduce the use of non-biodegradable substances which are harmful to us.
Example: Rather than using polythene sacks, we should give preference to paper bags.
(ii) Reuse: You should reuse the materials instead of discarding them.
Example: To create decorative stuff, plastic bags can be reused.
(iii) Recycling: The recycling process could include non-biodegradable products.
Examples: materials made of plastic.
(iv) Recovery: If the waste remains after it is reused and recycled, we can use it at our waste-energy (EfW) plant to produce energy. It's referred to as Rehabilitation.
Hence, the correct answer is option (A)

Note: As members of a nation, we have an obligation to sustainably manage our waste. Following the five R's of waste management, we should do this: decrease, reuse, recycle, recover and residual management.
