Answer 1

Answer:

a) cubic

Explanation:

The axial distances a, b, and c of cubic system are equal

ie. a = b = c

The axial angles α, β, γ of cubic system are also equal (90⁰)

$\alpha = \beta = \gamma = 90^\circ$

So the cubic system is most symmetrical, whereas the other systems show variation in either their axial distances, or axial angles, or both.
