Not in JEE Main or NEET syllabus

The crystal system of a compound with unit cell dimension a = 0.387, b = 0.387 and c = 0.504 nm and α = β = 90° and γ = 120° is

Answer: (B)

Solution

a = b ≠ c with α = β = 90° and γ = 120° are the parameters of the hexagonal system; cubic needs a = b = c, orthorhombic needs three
