Does the hydride ion, H, tend to behave as an acid or a base?

A) Hydride ion is unstable and re-reacts with water to form an acid in the form of the hydronium ion, H3O.
B) Hydride ion has a pair of electrons and acts like a Lewis base since it has a strong tendency to lend or donate that electron pair.
C) Although the hydride ion has two electrons, they do not pair together. Thus, the hydride ion is incapable of acting as a Lewis base and therefore tends to behave as an acid.
D) Hydride ion's makeup consists of one proton and two electrons. As such, its tendency is to form neutral hydrogen gas, , and therefore is neither acidic nor basic, but neutral.
