In the compound $M-O-H$,the $M-O$ bond will be broken if

• A
  $\Delta (E.N.)$ of $M$ and $O < \Delta (E.N.)$ of $O$ and $H$
• B
  $\Delta (E.N.)$ of $M$ and $O = \Delta (E.N.)$ of $O$ and $H$
• C
  $\Delta (E.N.)$ of $M$ and $O > \Delta (E.N.)$ of $O$ and $H$
• D
  Cannot be predicted according to $\Delta (E.N.)$ data
