P and Q are isomers of dicarboxyhc acid `C_(4)H4O_(4)` .Both decolourize `Br_(2)//H_(2)O` On heating, P forms the cyclic anhydride.
Upon treatment with dilute alkaline `KMnO_(4)`, P ass well as Q could produce one or more than one from S. T and U.
Compounds formed form P and Q are, respectively.
A. Optically active s and optically active pair (T,U)
B. Optically active S and optically inactive pair (T,U)
C. Optcally actve pair (T. U) and optically active S
D. Optically inactive pair (T. U) and optically inactive S
