For a cubic crystal structure which one of the following relations indicating the cell characteristics is correct?

Options

  1. Aa≠b≠ca \neq b \neq c and α=β=γ=90∘\alpha=\beta=\gamma=90^{\circ}
  2. Ba=b=ca=b=c and α≠β≠γ=90∘\alpha \neq \beta \neq \gamma=90^{\circ}
  3. Ca=b=ca=b=c and α=β=γ=90∘\alpha=\beta=\gamma=90^{\circ}
  4. Da≠b≠ca \neq b \neq c and α≠β\alpha \neq \beta and γ≠90∘\gamma \neq 90^{\circ}

Correct answer

C. a=b=ca=b=c and α=β=γ=90∘\alpha=\beta=\gamma=90^{\circ}

Step-by-step solution

In a cubic crystal structure a=b=c,α=β=γ=90∘a=b=c, \alpha=\beta=\gamma=90^{\circ}
