Ideal Gas question

Why is the answer D? In Chad's videos he said that kinetic energy has nothing to do with speed. He only mentioned the first two for the Kinetic molecular theory. So do ideal gases travel at the same speed as well?

Since they are in the same container = same temperature = same velocity.

It's kind of a poorly worded question in my opinion. I was under the impression that they all have the same AVERAGE velocity and that not all are necessarily moving at the same speed. Also, the question assumes that it's just talking about one type of gas because different types of gas have different speeds based on their respective weights. Have you checked the FAQ to see if there is any explanation there? I'm curious myself now.

I remember the fart and cologne analogy he used for that one haha
