Which Marvel Cinematic Universe Character Said It?

Do you remember who said these iconic lines?

Marvel Cinematic Universe is vast enough to forget it completely, but no matter how big it gets, we will never forget the iconic lines stated by the characters. And, if you don't pay close attention to dialogues, then I am sorry, but you will not be able to guess who owns these iconic lines in the quiz. And even if you do know, it will tough.   

So, take the quiz only if you are a true fan of Marvel Cinematic Universe.
