As from 4th and 5th option 7,8,3 are all wrong and in 1 and 2 we can see 6 no.is wrong so they all are wrong .Now we have 0,1,2,4.In 1st option as only 2 is the correct no. So it is the third digit.In option 3,2 and 0 are the only correct no.and 2 is the third digit and no. are wrongly placed so 1st digit is 0.In option 2 if the correct no.is placed wrong than it can't be 1so it must be 4. So the correct answer is 042
