Answer
A. high boiling points
Explanation
Substances that exhibit metallic bonding are characterized by the presence of a sea of delocalized electrons which allows for several distinct physical properties. Notably, metallic bonds result in high melting and boiling points due to the strong attractions between positive metal ions and delocalized electrons. These substances are typically not rigid and brittle; instead, they are malleable and ductile due to the ability of metallic atoms to slide past each other without breaking the metallic bond. Additionally, metals are generally excellent conductors of electricity because the delocalized electrons can move freely through the metallic structure.
