If \overline{a}=\overline{i}+\overline{j}+\overline{k}, \overline{c}=\overline{j}-\overline{k}, \overline{a} \times \overline{b}=\overline{c} and \overline{a} \cdot \overline{b}=3 then \overline{b}=

Correct Answer is : 13(5i+2j+2k)

\frac{1}{3}(5 \overline{i}+2 \overline{j}+2 \overline{k})

\frac{1}{3}(2 \overline{i}+5 \overline{j}+2 \overline{k})

\frac{1}{3}(2 \overline{i}+2 \overline{j}+3 \overline{k})

\frac{1}{3}(2 \overline{i}+5 \overline{j}+5 \overline{k})
