Which of the following solids generally have highest melting point?

Based on the nature of intermolecular forces, classify the following solid:

${\mathrm{SiO}}_2$

The number of network solids and ionic solids in the list given below is respectively

${\mathrm{H}}_2\mathrm{O}\left(\mathrm{ice}\right), \mathrm{AlN}, \mathrm{Cu}, {\mathrm{CaF}}_2 ,\mathrm{diamond}, \mathrm{MgO}, {\mathrm{CCl}}_{4,} \mathrm{ZnS}, \mathrm{Ag}, \mathrm{NaCl}, {\mathrm{SiO}}_2$

Match the following

        List - I                                      List-II
A) Metallic solid                         I) Carbon tetrachloride
B) Covalent solid                       II) Calcium fluoride
C) Molecular solid                     III) Copper
D) Ionic solid                             IV) Silicon carbide
                                                   V) Glass

The correct answer is
