Which air mass is maritime polar and typically brings cool, moist air?

Explanation:
Air masses are defined by where they form and how much moisture they carry. A maritime polar air mass forms over cold ocean waters at higher latitudes, so it picks up a lot of moisture while staying relatively cool. That combination—cool temperatures with high humidity—produces the cool, moist air described. It often brings overcast skies, fog, and light rain when it moves inland. The other types would be either drier or warmer, so they don’t match the cool, moist signature of maritime polar.
