Which of the following facts regarding bond energies is correct?

$\begin{array}{1 1}E_{O=O} < E_{S=S}\\E_{O-O} < E_{S-S}\\E_{O-H} < E_{S-H}\\E_{O-C} < E_{S-C}\end{array} $

Answer : $E_{O-O} < E_{S-S}$
Due to lone pair-lone pair repulsions on the neighbouring atoms,the single bond energies of O-O is smaller than that of S-S bond.
