The correct option is (C) : Interbreeding
A collection of creatures that may effectively interbreed to create viable offspring is referred to as a species. Therefore, regardless of environment, they are not reproductively separated. An organism's ecological niche describes its place in the ecosystem. There is no niche that is shared by two people. If they did, they would be vying for every resource, and the one who was more prepared to fill that niche would seemingly be able to kill the other. Every creature adapts to its surroundings in a unique fashion, with varying demands, interactions, and tolerance levels for various environments.
