Reason (R): They can be broken down by microorganisms in natural simple harmless substances.

Options

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R is not the correct explanation of A.

• A is true but R is false.

• A is false but R is true.

Answer 1

A is true but R is false.

Explanation:

Polythene bags and plastic containers are made of synthetic materials that cannot be easily decomposed by microorganisms. Therefore, they are classified as non-biodegradable substances and can remain in the environment for a very long time. Therefore, the Assertion is true.

ubstances that can be broken down by microorganisms into simple and harmless substances are called biodegradable substances, not non-biodegradable substances. Therefore, the Reason is false.

Hence, A is true but R is false.
