Explanation:
To know the the correct answer to the question given above, let us define the terms covalent and ionic.
Covalent is the term used to characterise a compound which is formed by sharing of electrons between the atoms involved. Thus, the compound formed is called covalent compound.
Ionic is the term used to characterise a compound formed when there is a transfer of electron(s) from the metallic atom to the non-metallic atom. The compound formed is called ionic compound.
