Solution:
Concept- A chemical bond between two atoms is the link between their atoms. In a chemical bond, the electrons are shared between the atoms which are linked together through those electrons.Chemical bonds can develop in a variety of ways. For example, an ionic bond forms when two ions are attracted to one another by an electric force, whereas a covalent link forms when two atoms share electrons. An enduring attraction between atoms, ions, or molecules is known as a chemical bond, and it is what allows chemical compounds to be created. Ionic bonds, which are formed by the electrostatic attraction of oppositely charged ions, and covalent bonds, which are formed by the sharing of electrons, respectively.
These two atoms are attracted to one another by this bond, which also serves as a link that allows them to coexist.
Hence, the correct answer is option 3.
