- Tourmaline
- Quartz
- Sodium Chloride
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
An optically active substance rotates the plane of polarized light. Quartz is known for its natural optical activity, while calcite and tourmaline only exhibit birefringence.
