If $\mathrm{P}=(\overline{\mathrm{a}} \times \overline{\mathrm{i}})^2+(\overline{\mathrm{a}} \times \overline{\mathrm{j}})^2+(\overline{\mathrm{a}} \times \overline{\mathrm{k}})^2$ and $\mathrm{Q}=(\overline{\mathrm{a}} \cdot \overline{\mathrm{i}})^2+(\overline{\mathrm{a}} \cdot \overline{\mathrm{j}})^2+(\overline{\mathrm{a}} \cdot \overline{\mathrm{k}})^2$, then

• A

  $P=Q$
• Correct answer
  B

  $P=2 Q$
• C

  $P=3 Q$
• D

  $P=4 Q$

Hence, the correct answer is option: 'B'.
