  • A a =b ≠ c ✔ ✖
  • B a = b = c and α = β ≠ γ = 90 ✔ ✖
  • C a = b = c and α = β = γ = 90 ✔ ✖
  • D a ≠ b = c and α = β ≠ γ = 90 ✔ ✖
Correct Answer

Explanation

A cubic crystal has three equal dimensions, a = b = c, and three angles, α = β = γ = 90. This is because a cubic crystal is a symmetrical structure, with each side of the cube being equal in length and each angle being equal in measure. The angles of a cube are all right angles, meaning that the measure of each angle is 90 degrees.
