Answer:
B. Ionic bond
Explanation:
Covalent bond is the bond which is formed with the sharing of the electrons between the two atoms which are taking place in the bond. It is generally formed between the atoms with similar electronegativity values.
Ionic bond is the bond which is formed between the two oppositely charged ions and are held by the strong electrostatic attraction. This is formed between the atoms which have high differing electronegativities.
In this kind of bond, the metal transfers one or more electron to the non metal which gain this electron and forms ionic bond.
Metallic bond is the bond which is formed by electrostatic attraction force between the positively charged metal ions and the conduction electrons.
Hydrogen bonding is a special type of the dipole-dipole interaction and it occurs between hydrogen atom that is bonded to highly electronegative atom which is either fluorine, oxygen or nitrogen atom.
Partially positive end of the hydrogen atom is attracted to partially negative end of these atoms which is present in another molecule. It is strong force of attraction between the molecules.
