Interpretation:

Among the given options, the one that describes a substance that function as an amphiprotic substance has to be given.

Concept Introduction:

Amphiprotic Substance:

It is a substance that can either accept a proton or lose a proton and hence can function as either a Bronsted–Lowry base or a Bronsted–Lowry acid.

The requirement of a substance to be a amphiprotic substance is the presence of both a lone pair of electrons and a hydrogen atom.  The most common example of amphiprotic substance is water.
