The correct combination of reagents A and B to effect the following transformations are 
<- B <- 
-- A --> 
<- B <- -- A --> (a)A = cat.OsO4, NMO B = i) $\mathrm{I_{2}}$, PhCO2Ag ii) aq.NaOH
(b)A = alkaline $\mathrm{KMnO_{4}}$ B = i) $\mathrm{I_{2}}$, PhCO2Ag, $\mathrm{H_{2}O}$ ii) aq.NaOH
(c)A = i) $\mathrm{I_{2}}$, PhCO2Ag ii) aq.NaOH B = cat $\mathrm{OsO_{4}}$, TMEDA, NMO
(d)A = m-CPBA, ii) aq.NaOH B = alkaline $\mathrm{KMnO_{4}}$
