To solve this question, the user needs to be familiar with programming and the concept of exit statements. Exit statements are used to prematurely terminate loops, functions, or procedures in a program.

Now, let's go through each option and explain why it is right or wrong:

A. Exit Do: This option is a valid exit statement in some programming languages, such as Visual Basic. It is used to exit a Do loop.

B. Exit For: This option is a valid exit statement in some programming languages, such as Visual Basic. It is used to exit a For loop.

C. Exit Form: This option is not a valid exit statement. "Form" is typically a term used in graphical user interface (GUI) programming to refer to a window or a user interface element. There is no standard "Exit Form" statement in most programming languages.

D. Exit Select: This option is a valid exit statement in some programming languages, such as Visual Basic. It is used to exit a Select Case or Switch statement.

E. Exit Sub: This option is a valid exit statement in some programming languages, such as Visual Basic. It is used to exit a Subroutine or Function.

Therefore, the correct answer is:

The Answer is: C. Exit Form
