उत्तर

A is false but R is true.

Explanation:

Not all the wastes mentioned are biodegradable. Paper, vegetable peels, and fruit peels are biodegradable, but plastic is non-biodegradable because microorganisms cannot easily break it down. Therefore, the Assertion (A) is false. 

Biodegradable wastes are those that microorganisms and other biological processes can decompose into simpler, harmless substances over time. Therefore, the Reason is true.

Hence, Assertion (A) is false, but Reason (R) is true.
