The vectors \overline{a}=2 \overline{i}+3 \overline{j}+6 \overline{k} and \overline{b} are collinear and |\overline{b}|=21, then \overline{b}=

Correct Answer is : ±(6i+9j+18k)

\pm(2 \overline{i}+3 \overline{j}+6 \overline{k})

\pm(6 \overline{i}+9 \overline{j}+18 \overline{k})

\frac{21}\sqrt{3}(\overline{i}+\overline{j}+\overline{k})

\pm 21(2 \overline{i}+3 \overline{j}+6 \overline{k})
