$\frac{[(\vec{a} \times \vec{b}) \times (\vec{b} \times \vec{c}), (\vec{b} \times \vec{c}) \times (\vec{c} \times \vec{a}), (\vec{c} \times \vec{a}) \times (\vec{a} \times \vec{b})]}{[\vec{a} \times \vec{b}, \vec{b} \times \vec{c}, \vec{c} \times \vec{a}]}$ का मान ज्ञात कीजिए।

• A
  $|\vec{a}|^2 |\vec{b}|^2 |\vec{c}|^2$
• B
  $[\vec{a}, \vec{b}, \vec{c}]^2$
• C
  $\frac{[\vec{a} \times \vec{b}, \vec{b} \times \vec{c}, \vec{c} \times \vec{a}]}{2}$
• D
  $\frac{|\vec{a}|^2 |\vec{b}|^2 |\vec{c}|^2}{2}$
