Which of the following is not a valid flow control statement?Optionsbreakexit()continuereturn

The option that is not a valid flow control statement is exit(). The other options - break, continue, and return - are all valid flow control statements in many programming languages.

Here's why:

1. break: This is used to terminate the current loop and resumes execution at the next statement after the loop.

2. continue: This is used in a loop control structure when you want to skip the rest of the current loop iteration and continue with the next one.

3. return: This is used to end the execution of the function call and "returns" control to the calling function.

4. exit(): This is not a flow control statement but a method that can be used to stop the execution of a program. It's not a statement that controls the flow of the program, but rather a function/method that is used to exit from the program entirely.
