Change or edit the following code so that it has 20 questions, there's an image for each question and once the user enters an incorrect answer, there's a button that the user can click on that displays the correct answer. The questions and answer choices should also be random each time you start the quiz.

Expert Solution

I have updated the code so now it will take 20 questions to end the quiz as you can see in the above screenshot. Questions will be asked randomly along with options which are jumbled among themselves like when I got the code to edit only option (a) was correct for every question but now it will generate random option for the correct answer.

If you selected the wrong answer you can view the correct answer by clicking on the answer button.

And the answer will be shown and you can move to the next question

If you have selected the correct option only score will get increased.

Now Code for this is given below:
