Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Sparged stirred-tank bioreactor allows better oxygen mixing compared to simple stirred-tank bioreactor. Reason (R): Sterile air bubbles sparged from the bottom dramatically increase the oxygen transfer area. 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.
