Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).\n Assertion (A): Selection of recombinants using chromogenic substrate (insertional inactivation of beta-galactosidase) is preferred over antibiotic resistance replica plating.\n Reason (R): Antibiotic selection requires simultaneous or consecutive plating on two different media plates, making it cumbersome. \nIn 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.
