I haven't tested this, but it may be possible to use a variable to do this. Of course, you'll need to know how to work with variables.
- The choices are selected states.
- When someone visits a slide, you can track the choice they made
- Thus when the quiz is reset and they revisit a slide you could use a trigger to select the question
- For example, have a variable for each choice:
- varChoiceA_Selected = False
- When they select the choice, have a trigger to change the var from false to true
- When they revisit the slide, you have a trigger that changes the choice to selected when the timeline of the slide starts on the condition that var = true
Something like that. There is some nuance because if a person clicks on all three choices before submitting, they could have all variables set to true, so you need to account for that
Here's some training on variables if you don't know how to work with them
