The following C$++$ function declares local variables X and Y:

$$ void MySub$()$

$\{$

$$ int X $=10$;

$$ int Y $=20$;

$\}$

a$.$

push$$ EBP

$$ mov$$ EBP, ESP

$$ sub$$ ESP, $8$

b$.$

mov EBP, ESP$$

$$ push EBP

$$ sub$$ ESP, $8$

c$.$

push EBP

$$mov ESP, EBP

$$sub$$ESP$,8$

d$.$

push$$ EBP

$$ mov$$ EBP, ESP

$$ add$$ ESP, $8$
