While surveying a rogue comet in deep space, an automated probe discovers pockets of four pure noble gases—neon, argon, krypton, and xenon—and records that xenon condenses into a liquid state at a remarkably higher temperature than neon despite both existing as neutral, nonpolar atoms. Which statement best explains why the intermolecular attractions between xenon atoms are much stronger than those between neon atoms?

A) Xenon has a larger and more polarizable electron cloud, which facilitates stronger temporary induced dipoles.

B) Xenon has a higher electronegativity value, enabling it to establish persistent permanent dipole attractions.

C) Xenon possesses more tightly held core electrons, creating permanent electrostatic repulsion that pulls nearby atoms inward.

D) Xenon atoms engage in directional hydrogen-like bonding due to their completely filled valence electron subshells.
