Consider the incomplete code.

The purpose of this CODE IS TO REMOVE AND RETURN the front element of the queue MYQ$.$

The main program calls the method ADDTOQ$()$ to add elements to the queue MYQ and the function REMOVEANDRETURN$()$ to remove and return the front element of the queue.

Indicate which of the following code $($ii$)$ will:$-$ correctly return the front element from the queue to the calling program$-$ remove the front element from the queue$-$ return the updated queue to the calling program.

You can assume that the ADDTOQ$()$ method works correctly.
