The ability to conduct electricity in the solid state is a characteristic of metallic bonding. this characteristic is best explained by the presence of

Explanation:

When positively charged metallic atoms share mobile electrons among themselves then the bond formed is known as a metallic bond.

Basically, a sea of electrons is formed by the mobile electrons in the metal cation.

For example, metals like copper, gold, silver etc form metallic bonds.

Also, it is known that current is the movement of free electrons from one point to another.

Hence, we can conclude that the ability to conduct electricity in the solid state is a characteristic of metallic bonding. This characteristic is best explained by the presence of mobile electrons.
