   A deep-space probe's atmospheric analyzer investigates four condensed trace compounds recovered from a cryo-containment vault: carbon tetrafluoride ($CF_4$), chloromethane ($CH_3Cl$), methanol ($CH_3OH$), and carbon dioxide ($CO_2$). The automated sorting system must isolate the substance that possesses a net molecular dipole and relies on permanent dipole–dipole attractions as its distinguishing polar interaction, while lacking conventional hydrogen bonds. Which substance correctly satisfies the analyzer's sorting criteria?

   • A) Carbon tetrafluoride ($CF_4$)
   • B) Chloromethane ($CH_3Cl$)
   • C) Methanol ($CH_3OH$)
   • D) Carbon dioxide ($CO_2$)
