Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R:

Assertion (A) : With global warming, organisms that were formally restricted to warmer regions will become more common towards the poles.

Reason (R) : Geographic distribution of organisms could not be significantly altered by climate change.

In the light of the above statements choose the most appropriate answer from the options given below 

 "A is correct, but R is not correct," it means you believe Assertion (A) is accurate, but Reason (R) is incorrect.

 Important Points

Assertion (A) is indeed correct. With global warming, organisms that were once restricted to warmer regions are becoming more common towards the poles. This is a well-established phenomenon driven by rising temperatures.

Reason (R) is considered incorrect in this context.

• While the geographic distribution of organisms can be significantly altered by climate change,
• Reason (R) suggests the opposite, that climate change couldn't significantly alter distribution.
• This contradicts scientific consensus and observations regarding the impact of climate change on species' ranges.

So,  "A is correct, but R is not correct,"
