Which of the following choices list the slides from the shortest to longest

cb, ab, ac
cb, ac, ab
ac, ab, cb
none of the choices are correct.

If they dont work in those orders than switch it up. Like instead of AC it would be CA.
These would be the different choices:
CA, BC, BA,
The reason I say this is because computers could have glitches or just be programed different. So try this instead.

Hope this helps : )***
