Right Hand Rule problems?

OK, well the question is attached, I just want help with Question 68, nothing is cut off from the photo.

All the answers say B, vertically down, and I don't see how unless I'm doing it so very wrong.  Doesn't Orientation 1 have to be A, Orientation 2 have to be D and Orientation 3 have to also be A since the current is flowing from K to L and the magnetic field is from left to right?

Sorry about the tilted image also

The answers are correct, they should all be B.

Your thumb should point towards the current, then your fingers will point in the same direction as the magnetic field, right, so then your palm will be pointing down and therefore the force will be down. And the current and magnetic field will always be going in the same direction so the force will always go in the same downwards direction too.

Don't no if that helps, but i tried.

Thanks StumbleBum, I just realised that I was using my thumb to point in the direction of the magnetic field and my fingers as the direction of current (*facepalm*).
