Assume the register rl holds $-/$ while another register r$2$ holds $+20$ for which both values are represented with the $2$s complement scheme, a student enrolled in ELEC $2441$ wrote the following ARM instructions to perform the index out$-$of$-$ bounds check for register r$1.$

CMP rl$,4$r$2$;

BGE IndexOutOfBounds;

Which of the following suggestions is correct about the above ARM instructions to perform the relevant check for register rl $?$

A$.$ the first instruction should be revised as $$CMP r$2,4$r$1$;$$;

B$.$ the second instruction should be revised as $$RE IndexOutOfBounds;$$;

C$.$ the second instruction IndexOutOfBound;s$$;

D$.$ the second instruction IndexOutOfBounds;$3$

E$.$ none of the above.
