Decarboxylation of all six possible forms of diaminobenzoic acids $C _{6} H _{3}\left( NH _{2}\right)_{2} COOH$ yields three products $A , B$ and $C$. Three acids give a product $'A',$ two acids gives a product $'B'$ and one acid give a product $'C'.$ The melting point of product $'C'$ is .....$^{\circ} C$.
