The correct answer is d. halogens, as they include elements that exist in solid (iodine), liquid (bromine), and gas (fluorine, chlorine) phases at room temperature. This unique characteristic distinguishes them from the other groups listed. Alkali metals, alkaline earth metals, transition metals, and noble gases do not exhibit such variation in phases.
