Which option correctly pairs a main air mass type with its source region?

Air masses carry the characteristics of their source region, so the labels reflect both moisture (maritime vs continental) and temperature (tropical vs polar). The maritime tropical air mass forms over warm tropical oceans, where abundant evaporation gives warm, humid air. That makes “maritime tropical from tropical oceans” the correct pairing. The other options mix regions that don’t match how these air masses form: maritime polar would come from colder, cloudy ocean areas in higher latitudes; continental tropical comes from hot, dry deserts in subtropical regions, not polar seas; continental polar comes from cold, dry continental interiors, not equatorial deserts.
