Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Smaller DNA fragments migrate faster and farther than larger fragments in an agarose gel. Reason (R): The sieving effect of the agarose gel allows smaller fragments to maneuver through the pores more easily. 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.
