Answer:
A
Step-by-step explanation:
A conductor works by allowing electrons to move through it with relative ease. In metals, this movement is facilitated by the structure of the material. Metals consist of a lattice of atoms in which the outermost electrons are not tightly bound to any particular atom. Instead, they are shared by all the atoms in the lattice and are free to move through the material. This allows electricity to flow freely through the metal, making it a good conductor.
