Answer:
Option (1)
Explanation:
Maritime polar air masses are normally characterized by the cool, moisture containing, unstable type of air mass, that are basically found in the higher latitudes, specially near the poles. It is designated as 'mP'.
This air masses also originates from the continental areas forming continental polar air masses over the region of Asia and it further moves in the western direction over the Pacific ocean. During this time of air, it attains the warmth and moisture from the Pacific ocean.
In addition to this, they also originate from the Northern side of the Atlantic Ocean and further move towards the southwestern direction and thereby reaches the Northeastern states.
Thus, in the given image, the air mass forming over the northern side of Antarctica is the Maritime polar air mass.
Hence, the correct answer is option (1).
