Develop an application to conduct a quiz test. When the quiz test is started, then a request is sent to the server end to retrieve the questions and the options for the quiz and display them to the user. Some questions have four options, and some have two or three options. Answer the following questions and write the appropriate scripts for the successful execution of the application on the browser. a) What is the most appropriate format to consider for the data transfer from the server to the user browser? And why? Write the corresponding script for your justification. (2 Marks) b) Write a script to check and validate the user inputs using JQuery for various questions. (2 Marks) c) Calculate the user's total score in real-time and save the options (make sure the user does not change the options if the entered option is the wrong answer and save the results in the server database.
