Here A=78

C,B=213

C,C=100

C,D=

o

C,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.
