Answer 1

A- Since it is really chemically seen as H+ -- O2- --H+. Looking at it this way, it can solvate the negative and form the hydroxide, or with positive to cause hydronium.

Answer 2

It has partial positive and partial negative charges, and so either side can face an ion - of opposite charge, of course. Answer "a".
