Answer
(ii) and (iii)
Reason — AgNO3 solution and copper metal will give displacement reaction where copper being more reactive than silver, displaces it from silver nitrate . Similarly, Al2(SO4)3 solution and magnesium metal will give displacement reaction where magnesium being more reactive than aluminium, displaces it from aluminium sulphate.
