Solution
The correct option is DO−H Heterolytic fission occurs when the two atoms differ considerably in their electronegativities. O-H bond undergoes cleavage most readily because O and H differ markedly in their electronegativity and further oxygen being highly electronegative can accomodate the negative charge more effectively developed after the cleavage. conclusion: hence option(D) is correct.
