Question

A crystal system having cell parameters $a eq b eq c$ and axial angles $\alpha = \beta = \gamma = 90^\circ$ is geometrically classified as:

Answer: D

💡 Solution & Explanation

The Orthorhombic (or Rhombic) crystal system is characterized by all three axes being of unequal lengths ($a eq b eq c$) while all three mutually perpendicular interfacial angles are exactly $90^\circ$ ($\alpha = \beta = \gamma = 90^\circ$).
