Hello, Christylucia96!! Your best answer would be C - Stellar evolution. Nuclear fusion is what powers the stars. Nebular clouds are a bunch of stars, also where they are born. Stellar means star and evolution means changes throughout time. The Big Bang Theory states that space began with a few stars and an explosion happened, which created a bunch of different stars that we have today. I hope I helped!! Have a great evening!!
I’m not completely sure but is it reproductive isolation?
