Issues with Gradings in chapter two: Upgrade operators

Hello, for the last lab question, I ticked set as an answer. Then it was showing me incorrect answer. So I hit Push and rename as other answers because I was expecting set to be wrong which I could not understand. then I hit Show answer and saw that set is the correct answer. How can it show fail if I hit the set operator?

Kind Regards,
Sophia

Hello Sonali, thanks for your reply. Yes I was first selecting $set and confirmed it. This was showing me wrong answer. That is why I selected others.

Kind Regards,
