Formation of covalent bonds in compounds exhibits

View answer and explanation

Correct option: A

Wave nature of electron

Option A (Wave nature of electron) is correct because covalent bonds are formed by the sharing of electrons, which is best explained by considering the wave nature of electrons and their ability to form standing waves between atoms.
