Answer

Brief Explanations:

A covalent bond is formed when a pair of electrons is shared between two atoms, meaning the electron - pair belongs to two atoms simultaneously. Option A describes the breaking of a bond rather than formation. Option C describes an ionic bond where electrons are transferred. Option D is about electron excitation within an atom and not bond - formation. Option E is not related to covalent bond formation.

Answer:

B. A pair of electrons belongs to two atoms at the same time.
