Solution

The correct option is A Mobile valence electrons
In metallic bonds positive kernels and delocalised (mobile) valence electrons have electrostatic attraction on all sides and hence do not have directional characteristics or are non -directional. The electrons form a sea around the metal atoms. Hence, the correct answer is option (a).
