<span>The answer is the option B. ionic bond. The ionic bond takes place when two ions of opposite charge (one positive and other negative) are bonded due to the electrostatic force between them. When sodium loses its valence electron it forms the positive ion (cation) Na+, and when chloride gains the electron lost by the sodium atom, it forms the negative ion (anion) Cl -, so these two ions form the ionic bond.</span>
