Here statement B is incorrect as${\mathrm{I}}_2{\mathrm{O}}_5$is unstable to heat
It decomposes when heated to$300°\mathrm{C}$.
$2{\mathrm{I}}_2{\mathrm{O}}_5\stackrel{300°\mathrm{C}}{\to }2{\mathrm{I}}_2+5{\mathrm{O}}_2$
Rest other statements are correct as follows
(i)$2\mathrm{H}\mathrm{I}{\mathrm{O}}_3\stackrel{170°\mathrm{C}}{\to }{\mathrm{I}}_2{\mathrm{O}}_5+{\mathrm{H}}_2\mathrm{O}$
(iii)${\mathrm{I}}_2{\mathrm{O}}_5$oxidizes CO to$\mathrm{C}{\mathrm{O}}_2$quantitatively at room temperature, liberating${\mathrm{I}}_2$, which can be titrated with sodium thiosulphate.
${\mathrm{I}}_2{\mathrm{O}}_5+5\mathrm{C}\mathrm{O}\to 5\mathrm{C}{\mathrm{O}}_2+{\mathrm{I}}_2$
(iv)$2{\mathrm{I}}_2+3{\mathrm{O}}_3\to {\mathrm{I}}_4{\mathrm{O}}_9$
$4{\mathrm{I}}_4{\mathrm{O}}_9\stackrel{>75°\mathrm{C}}{\to }6{\mathrm{I}}_2{\mathrm{O}}_5+2{\mathrm{I}}_2+3{\mathrm{O}}_2$
