Correct answer & explanation
✓
Screen2 does not exist in the app
If Screen2 does not exist, the Navigate function fails silently, causing the button to appear to do nothing. Option A is incorrect because the formula syntax is valid and parentheses are properly used. Option B is incorrect because navigation permissions are not enforced within the same app; any user can navigate between screens. Option C is incorrect because the app does not need to be published for the button to work in the editor or when running the app.
