Consider the following method, smallest, which is intended to return the smallest of three integers. It does not always work as intended.

public static int smallest$($int x$,$ int y$,$ int z$)\{$

if $(($x $<$ y$)$ && $($x $<$ z$))\{$

return x;

$\}$

else if $(($y $<$ x$)$ && $($y $<$ z$))\{$

return y;

$\}$

else $\{$

return z;

$\}$

$\}$

Which of the following identifies the condition in which smallest may not work as intended?

A$.$ smallest always returns the value of z$.$

B$.$ smallest may not work correctly when z has the smallest value.

C$.$ smallest may not work correctly when x and y have equal values.

D$.$ smallest may not work correctly when x and z have equal values.

E$.$ smallest may not work correctly when y and z have equal values.
