$A$ $\&$ $B$ are :

What is structure of $(A)$ ?
The original compound showed these properties also :
$\mathop {{C_9}{H_{12}}{O_2}}\limits_{(A)} \,\xrightarrow{{Na}}\,{H_2}$ liberated
$\mathop {{C_9}{H_{12}}{O_2}}\limits_{(A)} \,\xrightarrow{{Br}}$ no rapid reaction
$\mathop {{C_9}{H_{12}}{O_2}}\limits_{(A)} \,\xrightarrow[{cool}]{{Cr{O_3}\,/\,{H^ + }}}{C_9}{H_8}{O_3}$
$ {I_2} + 2{e^ - } \to \,2{I^ - }\,;\,\,{E^o}\, = \,\,0.54\,\,V $
$ MnO_4^ - \, + \,8{H^ + }\, + \,5{e^ - } \to \,M{n^{2 + }}\, + \,4{H_2}O\,;\,{E^{o\,}} = 1.52\,\,V $
$ F{e^{3 + }} + {e^ - } \to \,\,F{e^{2 + }}\,;\,\,{E^o}\, = \,\,0.77\,\,V $
$ S{n^{4 + }} + 2{e^ - } \to \,\,S{n^{2 + }}\,;\,\,{E^o}\, = \,\,0.1\,\,V $
The strongest reducant and oxidant respectively are
