Humans are known to have done something. Only A gets it right.

Dude,

Are you seriously having problem with these questions? Or are you just adding questions to increase your post count. If you are having problem with something specific in the question can you please post it along the question. This way people or instructors ( all of whom are really helpful) can clear your doubt.
