Consider inserting an integer element at an index of a Queue, select the best answer choice:

public void offer$($int data$)\{$

$//$Codes go here

$\}$

public void offer$($int data, int index$)\{$

$//$Codes go here

$\}$

public int offer$($int data$)\{$

$//$Codes go here

$\}$

Queue is a First$-$In$-$First$-$Out $($FIFO$)$ data structure and this operation is not supported.
