B )

Explanation:- According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.

Amphoteric substances are substances which can act as both acids and bases and thus can accept and donate ions.

Here water acts as an acid as it donates ions.

Here water acts as a base as it accepts ions.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
