P and Q are isomers `C_(4)H_(4)O_(4)` of dicarboxylic acid both decolorise `Br_(2)//H_(2)O`. On heating P forms the cyclic anhydride. Upon treatment with dilute alkaline `KMnO_(4)`, P as well as Q could produce one or more than one form S, T and U

Compounds formed from P and Q are respectively

A

Optically active S and Optically active pair (T,U)

B

Optically inactive S and Optically inactive pair (T,U)

C

Optically active pair (T,U) and optically active S

D

Optically inactive pair (T, U) and optically inactive S
