The answer here is D, and it's kind of obvious. But you probably already knew the answer and are just doing this for piece of mind.

Explanation: Just the fact that we don't know whether or not there even is extraterrestrial life rules out every other answer, without even needing to go in depth.

(Okay, I read your question completely wrong, it's asking for which one of these has been solved isn't it?)

This is tough because all of these other than D have been figured out. Go with the methane atmosphere then.
