A unit vector perpendicular to the plane of
\( \mathrm{P} \) \( \vec{a}=2 \hat{i}-6 \hat{j}-3 \hat{k} \) and \( \vec{b}=4 \hat{i}+3 \hat{j}-\hat{k} \), is:

W.
(1) \( \frac{1}{\sqrt{26}}(4 \hat{i}+3 \hat{j}-\hat{k}) \)
(2) \( \frac{1}{7}(2 \hat{i}-6 \hat{j}-3 \hat{k}) \)
(3) \( \frac{1}{7}(3 \hat{i}-2 \hat{j}+6 \hat{k}) \)
(4) \( \frac{1}{7}(2 \hat{i}-3 \hat{j}-6 \hat{k}) \)
