Answer:
Option c. is correct
Explanation:
A chemical bond enables the formation of chemical compounds depending on the nature of the participating atoms like atoms, ions or molecules.
These are formed as a result of the force of attraction between oppositely charged ions.
It is formed by the overlapping of the atomic orbitals of the two atoms.
When the length of a chemical bond is short an electron is held tighter and the bond is stronger
