Unit vectors  $\begin{array}{l}\overline{a,}\hspace{0.25em}\overline{b,}\hspace{0.25em}\overline{c}\end{array}$  are coplanar. A unit vector $\begin{array}{l}\hspace{0.25em}\hspace{0.25em}\hspace{0.25em}\overline{d}\end{array}$  is perpendicular to them
If $(\overline{a}\times \overline{b})X(\overline{c}\times \overline{d})=\frac{1}{6}i-\frac{1}{3}j+\frac{1}{3}k$   then which of the following vectors are parallel to  $\begin{array}{l}\hspace{0.25em}\hspace{0.25em}\hspace{0.25em}\hspace{0.25em}\overline{c}\end{array}$
