💡 Solution & Explanation

Metallic bonds are non-directional, allowing atoms to pack as closely as possible, frequently adopting HCP or CCP structures with a maximum coordination number of 12. Covalent bonds are directional, and ionic bonds involve differently sized, charged ions subject to repulsion, preventing them from achieving this close-packed arrangement. Therefore, correct answer is A.
