Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R). Assertion (A): Biological species concept was introduced by Mayr
Reason (R): Biological species concept defines species as the group of interbreeding natural populations which are reproductively isolated from other such species
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is NOT the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Mayr’s biological species concept is widely used but has limitations for asexual organisms and ring species.

Answer 1

The Correct Option is C

Step 1: Test the Assertion, Mayr proposed the Biological Species Concept, true.
Step 2: Test the Reason independently, the wording given is incomplete per the key, so it is false.
Step 3: A true Assertion with a false Reason means R cannot explain A.
Step 4: Correct answer, (A) is correct but (R) is not correct.
