The correct answer is A,  the valence electrons move between atoms in shared orbitals. The result of millions of metal atoms crowding together so that molecular orbitals become combined most likely is the formation of localized valence electrons where the electrons are called the "electron sea". This is a characteristic of compounds that are held together by metallic bonding.

The correct answer is A
