Column I	Column II
(A) Angle between any two solid diagonal	(p) $\cos^{-1} \frac{2}{\sqrt{6}}$
(B) Angle between a solid diagonal and a plane	(q) $\cos^{-1} \left( \frac{1}{2} \right)$
(C) Angle between plane diagonals of adjacent faces	(r) $\cos^{-1} \frac{1}{3}$
(D) The values of $\mathbf{a} \times \mathbf{b}$	(s) $\frac{1}{2}$
