Answer:
A. The probable direction of storm movement for the next 12 hours.
Step-by-step explanation:
In the northern hemisphere, air circulation is counterclockwise around a low pressure system. The arrow drawn on the diagram is below (south of) the center of low pressure, so the winds will be to the east in that area. The arrow is pointed in the direction of probable frontal system movement.

Other answer choices:
The map is of a portion of the eastern part of the North American continent. There is no ocean in the area of the frontal system or the arrow, so ocean currents are irrelevant to what the arrow is showing.
Convection currents in the atmosphere are vertical air currents. The horizontal arrow cannot show anything about convection currents.
Due to jet stream and trade wind direction over North America, the storm system shown would have originated farther to the north and west. The arrow points to the east northeast, so is not pointing in the direction of the origin of the storm system.
