The correct electronic configuration for the product of the reaction between potassium (K) and chlorine (Cl) to form K+ and Cl- is the configuration of Cl-, which gains one electron to complete its valence shell, resulting in the configuration (1s^2 2s^2 2p^6 3s^2 3p^6). This matches choice C, which represents a filled valence shell similar to that of an argon atom, indicating a stable, negatively charged chloride ion (Cl-).
