D Sn

Dear Student,

Quartz is extensively used as a piezoelectric material as it contains silicon.
The chemical formula for quartz is SiO₂.
Silicon acts as a piezoelectric material due to the particular arrangement of Si and O atoms in quartz.

Thus, the correct answer is option (b).

Hope it helps.
