Which statements are correct?

AIce is a molecular solid in which molecules are held by hydrogen bonds.
BGraphite is a covalent solid that conducts electricity along its layers.
CSilicon carbide is an ionic solid.
DCrystalline quartz shows anisotropy.

Answer: A, B, D

Ice: molecular solid with hydrogen bonds. Graphite has delocalised electrons within the layers. SiC is a covalent network solid, not ionic. Quartz is crystalline, so its physical properties depend on direction.
