I think C) Income is the way to go. Unless the decision tree is being built by a bunch of accountants - then maybe A) Credit Score would be the winner.

I'm going with C) Income. It's the obvious choice here. Although, if this were a dating app, I'd pick D) Gender. You know, for science!

Hmm, I'm not sure. What if the decision tree is trying to predict gender? Then maybe D) Gender would be the best choice. Just a thought!

Definitely C) Income. That's the one with the biggest number, so it must be the best choice for the next split.
