C Correct answer
Explanation

In covalent bonding, the outer electron shells (orbitals) of two bonded atoms overlap to allow sharing of electrons. This orbital overlap creates a region of high electron density between the nuclei, which holds the atoms together. The extent of overlap influences bond strength and molecular geometry.
