Solution

The correct option is D OH
Heterolytic fission occurs when the two atoms differ considerably in their electronegativities.
OH bond undergoes cleavage most readily because O and H differ markedly in their electronegativity and further oxygen being highly electronegative can accommodate the negative charge more effectively developed after the cleavage.
