    Answer.
    (a) B is the most reactive metal
    (b)If B is added to a solution of copper
    (II) sulphate, displacement reaction
    will take place. Blue colour of copper
    sulphate will fade and red –brown
    copper will settle down.
    (c) The decreasing order of reactivity is:
    B> A> C >D
