I've just implemented the code for my multiple-choice question (MCQ) website. One of the key features I want to include is immediate feedback when a user selects an answer - indicating whether it is correct or incorrect along with showcasing the correct answer if needed. Additionally, once the correct answer is revealed, there will be no second chance given to select an already shown correct option. This ensures that users cannot change their choice once they have seen the correct answer. Below is the code snippet:
