Answer: Option (b) is the correct answer.
Explanation:
A chemical bond which is formed by sharing of electrons is known as a covalent bond.
For example, hydrogen has electronic configuration [tex]1s^{1}[/tex] and electronic configuration of chlorine is [tex]1s^{1}2s^{2}2p^{6}3s^{2}3p^{5}[/tex].
Thus, from the electronic configuration it can be seen that both hydrogen and chlorine need one electron in order to complete their octet. Therefore, both will share an electron.
As a result, a covalent bond will be formed.
Hence, we can conclude that the statement electrons are shared is the true statement about covalent compounds.
