Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Plasmids are extrachromosomal, autonomously replicating circular DNA molecules found in bacteria. Reason (R): Plasmids possess an origin of replication (\( \text{ori} \)) which enables them to multiply independently of chromosomal DNA control in host cells. In the light of the above statements, choose the correct answer from the options given below:

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