Hello!

If you look at a zipper, you'll see that it doesn't have a wheel or an axle. A zipper links the <span>protruding teeth that the zip contains. Your answer would be B!

You can feel free to let me know if you have any questions regarding this!
Thanks!

Zipper, because it's two inclined planes that form into wedges rather than being a wheel and axle.
