test al, 00000010b
mov al, 00000110b
cmp al, 00000101b

Answer:

CF  = 0

ZF = 0

SF = 0

Explanation:

Assuming that at the initial stage that all Flag values are = zero

every Instruction sequence will have the values of CF , ZF and SF = 0 respectively

i.e.

CF = 0

ZF = 0

SF = 0

This is because the instruction "mov" in the instruction sequence does not have an effect on the flags. until when the accumulator is loaded with the value zero
