Match appropriately the information given in three columns of following table.
Let OABC be a tetrahedron such that foot of perpendicular from O to the side AB meets at its midpoint M. If  $\left|\overrightarrow{OA}\right|=p=\left|\overrightarrow{CM}\right|,\left|\overrightarrow{AB}\right|=q,\overrightarrow{CA}.\overrightarrow{AM}=0$.
Column–1: Contains values of p and q.
Column–2: Contains maximum volume of tetrahedron OABC when base is  $\Delta ABC$.
Column–3: Contains height of tetrahedron, when volume of tetrahedron is same as in previous case and base is  $\Delta OAB$.
