Solution

The correct options are
A Covalent bonding
B Hydrogen bonding
Option (A) and (B) are correct.
The physical properties of quartz are due to covalent bonding and hydrogen bonding.
Each silicon atom is covalently bonded to four oxygen atoms. Each oxygen atom is covalently bonded to two silicon atoms.Thus all atoms in the entire crystal are linked together by covalent bonding which makes quartz hard, brittle, and have high melting points.
When quartz molecules are built up to form crystals and silicates, several linked SiO4 units with attached hydrogen by hydrogen bonding.
