Solution

The correct option is D giant polymer structure with strong covalent bonds
Diamond has a polymeric structure with multiple $C - C$ single bonds. The bond energy of each $C - C$ single bond is very high. To melt diamond, these bonds are to be broken, to increase the intermolecular separation. As high temperatures are required to break such strong bonds, diamond melts at a very high temperature.
