correct option is 4.
 
Only Aluminium can extent its valency because it has empty d-orbitals, whereas carbon and boron do not have d-orbitals to extend their valency.
Hence reactions given in option (1) and (2) are not possible.

A gas is obtained by the reaction of magnesium nitride with water. It acts as a lewis base and turns red litmus blue. It reacts with CuO as a reducing agent. It is obtained from two elements by reacting at 700K and high pressure. It is highly soluble in water. It forms blue coloured solution with copper sulphate. Identify the gas and write all the reactions involved.
