Consider the following arithmetic operations in C:

int $x=20$;

int $Y=20$;

int $Z=2**(x+Y)$

which assembly code $(086)$ does not evaluate value for $Z$ correctly?

mov ebx, Y

add eax, ebx

mov cl$,2$

imul cl

mov Z$,$eax

mov eax, $x$

mov ebx, Y

add eax, ebx

mov cl$,4$

imul cl

shi eax, $1$
