Assume the following method is added to the ArrayStack class. What does this method do?

public ArrayStack Undefined()

{

int j = 0;

ArrayStack st1= new ArrayStack(topOfStack + 1);

for(int i = 0; i < topOfStack + 1; i += 2)

{

st1.theData[j] = theData[i];

j = j + 1 ;

}

return st1;

}

	a.	The method will return a stack containing all the elements of this stack in the same order.
	b.	The method will return a stack containing the alternative elements of this stack in the reverse order.
	c.	The method will return a stack containing the alternative elements of this stack in the same order.
	d.	The method will return a stack containing all the elements of this stack in the reverse order.
