Answer: CF = 0 ZF = 0SF = 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 respectivelyi.e. CF = 0 ZF = 0SF = 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
