C Correct answer
Explanation

Isolation is a key factor in speciation as it prevents gene flow between populations, allowing them to diverge genetically over time. Geographic, reproductive, ecological, or behavioral isolation mechanisms enable populations to evolve independently, eventually leading to the formation of new species. Without isolation, interbreeding would maintain genetic similarity.
