AI Explanation

To display the message "Hello World" in an alert box, you would use the alert() function.

Let's go through each option to understand why it is correct or incorrect:

Option A) alertBox="Hello World" - This option is incorrect because there is no built-in function called alertBox(). The correct function to display an alert is alert().

Option B) alertBox("Hello World") - This option is incorrect for the same reason as Option A. There is no alertBox() function.

Option C) alert("Hello World") - This option is correct. The alert() function is used to display a message in an alert box, and "Hello World" is the message to be displayed.

Option D) msgBox("Hello World") - This option is incorrect because there is no built-in function called msgBox(). The correct function is alert().

Therefore, the correct answer is option C.
