How do you stop learned behavior when testing very similar scenarios?

I am running some usability tests in the coming days. I have three options of one feature for a pretty simple and quick test.

My concern is that because each of the options are very similar to each other, once the user understands how the first one works the other two would be easy to figure out.

I will be rotating the options so as to not start with the same test each time.

My goal is to find out which option makes the most sense and is easiest for them to complete a particular task.

Any advice would be appreciated.
