Witch of the following protists uses cilia for locomotion?

I'm guessing ciliates but I can't know for sure without your multiple choice options. If ciliates is an option, that would be it.

It depends on the surface of the levels. the rougher the surface, the greater is the frictional force. for rougher surfaces, you would need to exert greater force to move the object. the concept is that, you must overcome the frictional force in order to bring the object into motion. this is the reason why we add lubricants to the joints so they could easily move. this answer was on
