Accepted Answer

Short answer is that Qu'est-ce que c'est . .   and C'est quoi . .  are both correct ways of asking "What is (that) . . . . However, as one of the responses you note as being stated to be correct («Est-ce que c'est») is not, there is clearly a problem somewhere. With quiz issues, it is always better to submit through "Report an Issue", even if also posting here. Sometimes the error is in the program, sometimes it is the operator (been there, done that).
