Multiple choice: Select one The multiple-choice (select one) question type lets respondents choose only one answer from a set of options.
When you add questions to a survey, the validation option is turned off by default. This means respondents can skip questions and still complete the survey. If they go through all the pages without answering, the survey will still be marked as complete. You can turn on validation to make certain questions required, ensuring respondents must answer them before moving on.
When you enable validation, you'll see options for "Force Response" and "Request Response." By default, "Force Response" is selected, making the question mandatory. If you choose "Request Response," the respondent will get a pop-up if they skip a question, asking if they want to answer it or continue without answering.
