Use the Answer Order Property to change the order of the answers on multiple choice questions in an assessment.
If the Answer Order Property is set to As Authored, answers are presented in the order in which they were created in Developer.
If the Answer Order Property is set to Random Order, answers to multiple choice questions are provided in random order. The answers appear in a different order each time the question is presented. For Multiple Choice (single answer) questions that include All of the Above and/or None of the Above, these answers remain in their positions at the bottom of the list of choices.
Note: The default answer order is set on the Answer Order option in the Assessment category on the Options dialog box.
