Which of the following cannot be regarded as molecular solid ?

(a)SIC (silicon carbide) (b) AIN

(c) Diamond (d) $I_2$

$SiC,AlN$ and diamond are examples of network solid as they have three-dimensional structure while $I_2$ is a molecular solid because such particles are held together by dipole-dipole interactions.
