Explanation:
Here A=78 oC,B=213 oC,C=100 oC,D= oC,154 C have melting points.
As stronger the faces of attraction between the particles more will be melting point and vice-versa.
Hence,
Order of their inter-particle forces of attraction is B>D>C>A maximum melting point, so maximum inter particles forces of attraction
