Vapor pressure is influenced by intermolecular forces; the weaker these forces, the higher the vapor pressure. CH₄ (methane) has the weakest intermolecular forces (dispersion forces) among the options, as it is the smallest molecule with the least polarizable electron cloud, leading to the highest vapor pressure at a given temperature.
