• D. Both A and R are correct but R is not the correct explanation for A.

Answer 1

The correct option is D Both A and R are correct but R is not the correct explanation for A.

Speciation is a very slow process and it results in evolution. It is the process of formation of new species. Variations in the gene pool (sum total of all genes) of an organism can arise due to geographical isolation, genetic drift, natural selection, etc. This results in the formation of new distinct species. This process is very slow and takes millions of years.
