Question
Assertion (A): Recycling is the way of managing plastic waste.
Reason (R): Broken plastic articles are sent to plastic processing units where they are melted and remoulded to make new plastic articles.

Answer

(b) Both A and R are true but R is not the correct explanation of A.
Explanation: Plastics are non-biodegradable. They cannot be decomposed by the action of microbes. Recycling them can
manage them effectively.
