How to create a Multiple Choice Question Content Type.
For Ex:
Q1. What is color of Mango?
Option 1: Green
Option 2: Yellow
Option 3: Blue
Option 4: White
Correct Answer is Option 2
Are you trying to create a quiz that responds with the correct answer? There would be several steps involved in that. You could use the apostrophe-forms module to create a form for this, then use the select field type for the question.
To have it respond with the correct answer, you would need to extend or improve apostrophe-forms (see “You’ll need to use the improve option.” on this page for more). Each field widget would need a new field added for the correct answer, then front end code to reveal it on submission.
So this is not a ten minute project, but it would be doable and interesting.
