If $\vec{A}=4\hat{i}+3\hat{j}+\hat{k}$ and $\vec{B}=2\hat{i}-\hat{j}+2\hat{k}$ , then the unit vector $\hat{N}$ perpendicular to the vectors $\vec{A}$ and $\vec{B}$ ,such that $\vec{A}, \vec{B}$ , and $\hat{N}$ form a right handed system, is:
A.
$$\frac{1}{\sqrt{185}}(7\hat{i}-6\hat{j}-10\hat{k})$$
B.
$$\frac{1}{7}(6\hat{i}+2\hat{j}+3\hat{k})$$
C.
$$\frac{1}{\sqrt{21}}(2\hat{i}+4\hat{j}-\hat{k})$$
D.
$$\frac{1}{\sqrt{21}}(-2\hat{i}-4\hat{j}+\hat{k})$$
