${B{orax}}\xrightarrow{X}{H_3}B{O_3}\xrightarrow{\Delta }{B_2}{O_3}\xrightarrow[\Delta ]{Y}B$,
$X$ and $Y$ are respectively
$CH_3 - CH_3, CH_3 - CH_2 $$- CH_3, (CH_3)_2CH - CH_3,$
$ CH_3 - CH_2 - CH(CH_3)_2.$
Increasing order of stability of the radicals is
$(B)$ $I _{2}+ H _{2} O _{2}+2 OH ^{-} \rightarrow 2 I ^{-}+2 H _{2} O + O _{2}$
Choose the correct option.
