On the ROM-based microcontroller quiz page, when a user selects an option, it correctly turns red (wrong) or green (correct).
However, the quiz has two major issues:
Users can continue clicking other options even after selecting an answer.
Each click changes the button state, so multiple options can appear red/green one after another.
When a wrong answer is selected, the quiz does not automatically highlight the correct option in green.
This makes it unclear what the right answer actually is.
--Expected Behaviour
After the user selects an answer:
Only one option should be marked (red for wrong or green for correct).
All other options should become disabled.
If the selected answer is wrong:
The correct answer should automatically be highlighted in green.
--Actual Behaviour
User can keep selecting different answers even after the first click.
No lockout mechanism after answering.
When a wrong answer is chosen, the correct answer is not shown automatically.
UI becomes confusing because multiple buttons can be clicked and re-colored.
--Impact
Poor quiz experience and unclear feedback to users.
Users cannot tell which option is the correct one after making a mistake.
Makes the interactive book feel inconsistent with typical MCQ quiz behaviour.
Describe the solution you'd like
--Disable all answer buttons immediately after the first click.
--Apply appropriate styling:
Selected option → red or green
Correct option → green (always shown, even after wrong selection)
Describe alternatives you've considered
Optionally add a “Try Again” or “Reset Question” button.
