Solution
The correct option is D all of the above Metallic bond is the force of attraction between many valence electrons and positive ions such that a single electron is attracted by many positive ions (also known as kernel). Hence it is non-directional and non-saturable.
Whereas covalent bond is formed by sharing of valence electrons between two particular atoms which makes it directional as well as saturable.
