- Zinc blende
- Graphite
- Cinnabar
- Potassium dichromate
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Graphite has a hexagonal crystal structure where a = b ≠ c and the angles α = β = 90°, γ = 120°. This structure contributes to its unique layered properties, which are characteristic of hexagonal systems. The other options do not satisfy these structural parameters.
