In a Survey, is there there an option to deactivate one possible answer option from a question?

Hi salacho ,
What I have done in a situation like this is to set up Display Logic in the choice I want to deactivate. Make the condition something that will be constant so there is no chance the Display Logic will go any other way. For instance, if the first question in your survey is always displayed, make this Display Logic something like "If Q1 is Not Displayed".

Thank you MatthewM.
Unfortunately, we already have display logic for each answer option. We actually seek disabling one of the answer options to avoid having the responders answering the questions triggered by such display logic.
I hope there is a way to disable (or gray-out) one answer choice.
Cheers!

You can select display logic in true-false as false and it won't be visible to the respondents.
