The following instructions are from an assembly programming script written for $8086$ microprocessors.

MOV $AL,05H$

$($Given algorithms:

SUB $AL,01H$

MOV operand $1,$ operand$2$: operand $1=$ operand$2$

SUB operand$1,$ operand$2$: operand$1=$ operand$1-$ operand$2)$

What do we find in the carry flag $($CF$)$ and the zero flag $($ZF$)$ after the operations?

$CF=0,ZF=1$

$CF=1,ZF=0$

$CF=0,ZF=0$

$CF=1,ZF=1$
