Solution

The correct option is B electrostatic force
B. Electrostatic force
Ionic bonding is the electrostatic force of attraction between positively and negatively charged ions. The ions have been produced as a result of transfer of electrons between two atoms with a large difference in electronegativity. As the ionic bond is a strong bond high energy is required to break the bond. Hence high temperature is needed to indicate the nucleus fusion reaction.
