Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): For smaller, restricted geographic regions, the value of the regression coefficient (Z) lies between 0.1 and 0.2, regardless of the taxonomic group. Reason (R): The slope of the species-area curve becomes significantly steeper when analyzed over entire continents. 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.
