You can do this a few different ways, there isn’t an option like limit choice selection to the number of correct answers. Let me know if that is what you are trying to do, and if you would like it or some other use case as a built in feature.
I am including a Lectora Online PKG file which can be imported into either Desktop or Online. There are two examples on how to accomplish this using Lectora Actions and Variables. See if one of them will work for you.
