Solution

The correct option is D attractive forces


The two main ways in which atoms can be combined to form molecules are by electrovalent bonds and covalent bonds.
Electrovalent bonds are held together by an electrical attraction between positively charged cations and negatively charged anions.

The Valence Bond theory describes the formation of covalent bonds from the overlap of atomic orbitals on two different atoms. Because of the overlap, it is highly probable that a pair of electrons are found in the physical region or space where the orbitals overlap.
