Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Restriction endonucleases inspect the length of a DNA sequence to find their specific recognition sites. Reason (R): Restriction endonucleases cleave both strands of DNA at random positions without sequence specificity. 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.
