Consider the function:

int mystery($($int w)$)$

{$\{$

if ($($w <0)$<0)$

return 0$0$;

int x =$=$ mystery($($w −2)$-2)$;

return w −$-$ x;

}$\}$

Which line's removal would cause infinite recursion?

Question 29$29$ options:

A)$)$

int mystery ($($int w)$)$

B)$)$

if ($($w <0)$<0)$ return 0$0$;

C)$)$

int x =$=$ mystery ($($w −2)$-2)$;

D)$)$

return w −$-$ x;

E)$)$

The recursion is already infinite.
