C# - Can a public function argument be a selection of public static variables?

Just a quick question to know whether or not this is possible.

I like to keep the habit of being DRY with my coding, so i don't like to recreate the same function, just to change one variable name. For example, I have a lot of buttons, and each one does the same basic function but for different GameObjects, example:

 public void pressedSoundOptionButton() {
     if (soundsOption) {
         soundsOptionMarker.SetActive (false);
     } else if (!soundsOption) {
         soundsOptionMarker.SetActive (true);
     }

I have buttons that attach to these public functions, But what i'd like is that each button can use the same function, but pass an argument telling it which variable and GameObject to check for. (Maybe two arguments)

IS it possible to do something like:

     public void pressedOptionButton (bool.name BooleanToUse) {
 //do stuff with the boolean variable given to this function
 }

Obviously i can't do (string varName), But I could always pass a string, and then lay out a long list of if's saying if (string == "var1") { booleanTouse = var1; But i feel like that would be bad practice.

(Also I'm new to C#) Whats the genius way of doing this?
