Disposable plastic plates should not be used because :(a) they are made of light weight materials (b) they are made of toxic materials(c) they are made of biodegradable materials (d) they are made of non-biodegradable materials
Correct answer: (d) they are made of non-biodegradable materials.
Explanation: Disposable plastic plates cannot be degraded by micro-organisms and hence should not be used as they will remain in the environment and pollute it.
