Select the correct option based on statements below:

Assertion (A):	Most of synthetic polymers are not biodegradable.
Reason (R):	The polymerization process induces toxic character in organic molecules.

1.	Both (A) and (R) are true but (R) is not the correct explanation of (A).
2.	Both (A) and (R) are true and (R) is the correct explanation of (A).
3.	Both (A) and (R) are false.
4.	(A) is true but (R) is false.

HINT: Synthetic polymers are not biodegradable.

Explanation:

Biodegradable polymers are a special class of polymer that breaks down after its intended purpose by the bacterial decomposition process.

Most synthetic polymers are not biodegradable because they are not easily broken by soil organisms and are hazardous to the environment.

The polymerization process induces toxic character in organic molecules is the wrong statement.
