(Text Quest) How to make an action available (via c#.unity) only if there were 3 specific answers selected before?

Question

C++ / C#

Hello, I hope for help, the fact is that I don’t know how to implement such a thing, at first I planned to make an int MC variable that would be responsible for the relationship of the character to the player. Depending on which answer the player chose. MC + 1, or -1, or nothing. Then, when the button (UI) is pressed, there should be a check, that is, a separate method is allocated for it. How can I check a variable?
3 defined responses - this means that the action is only performed if MC = 3;
This moment is very important for me because a lot of things are tied to this in the game. Please, if I wrote something unclear, write, I will clarify everything ...
