Question

Assertion (A): Plastic substances and mineral wastes are non-biodegradable.

Reason (R): As these substances cannot be broken down by biological or microbial action, they are called non-biodegradable.

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

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

Explanation:

Plastic substances and mineral wastes are non-biodegradable because microorganisms and other biological processes cannot decompose them naturally. Therefore, the Assertion (A) is true.

The Reason (R) is also true because substances that cannot be broken down by biological or microbial action are called non-biodegradable substances. This directly explains why plastics and mineral wastes are classified as non-biodegradable.

Hence, both A and R are true, and R is the correct explanation of A.
