Pure copper metal, \(\text{Cu(s)}\), is widely used in electrical applications because it conducts electricity efficiently and can be drawn into thin wires (ductile) without fracturing. Which of the following particulate-level descriptions best justifies these macroscopic properties of copper?

- **A.** Copper exhibits these properties because rigid, directional covalent bonds hold \(\text{Cu}\) atoms in fixed positions while localized valence electrons vibrate to carry electric current.
- **B.** Copper exhibits these properties because alternating cations and anions readily shift across lattice planes while mobile anions carry electric current.
- **C.** Copper exhibits these properties because neutral \(\text{Cu}\) atoms are held together only by weak London dispersion forces that break readily, allowing individual atoms to slide and conduct charge.
- **D.** Copper exhibits these properties because delocalized valence electrons move freely through the lattice under an applied electric potential, and non-directional metallic bonds allow planes of \(\text{Cu}\) cations to slide past one another without shattering.
