Abhinav a class 9 student arranged the given setup to study the reactivity of some metals with water .he summerised his observations as follows: 1.In test tube p,there was no reaction in cold water but when th etest tube was heated for a while bubles of gas was seen. 2.In test tube Q,bubbles of gas were formed only after boiling the water . 3.In test tube R,no gas was produced even on boiling the water. 4.In test ube S,reaction occured vigirously. The metals present in P,Q,R,S could be respectively A.Na,Mg,Zn,Fe B.Na,Mg,Al,Cu C.Mg,Zn,Cu,Na D.Mg,Zn,Fe,Al
