I really have a hard time understanding this lack of "meta-intelligence" (or should we say "street smarts", that'd explain the success of at least some of your non university educated friends)

While it's evident that D is nonsensical, it's just as obvious that it is indeed the intended answer.

I expect if you are smart enough to detect it is nonsensical, you are also smart enough to deduce what you are expected to answer. I fail to understand why people nitpick themselves to death by a million cuts.

Maybe I'm not smart enough!
