Explanation:

Metallic bonds occur between metal atoms. In metallic bonding, electrons are delocalized. They are not strongly attracted to individual nuclei (as metals have relatively low ionization energies and don't hold valence electrons tightly). These delocalized electrons form a "sea of electrons" that move freely around the metal nuclei.

• The first option is wrong because metallic bonds are between metal - metal atoms, not metal - nonmetal. Also, electrons are not held in rigid structures in metallic bonds.
• The second option is wrong because electrons are not transferred (that's ionic bonding) and not held in rigid structures.
• The fourth option is wrong because metallic bonds are between metal atoms (not metal - nonmetal) and the concept of octet rule (which is more relevant to covalent and ionic bonds for non - metals to achieve a stable electron configuration) is not the reason for the sea of electrons in metallic bonds.

Answer:

The electrons are shared by all the nuclei because the electrons are not strongly attracted to the atoms' nuclei and therefore move around freely between the metal atoms.
