Correct answer: (c) B Explanation: Test-tube I, iron filling is added in aluminium sulphate solution, no colour change will be observed as iron is less reactive than aluminium, so it cannot displace aluminium from its sulphate solution. Hence, no reaction takes place. Test-tube II, iron filling is added in copper sulphate solution, blue colour changes to light green.
