Which option identifies the two natural wind patterns that move air masses in the United States?

The United States is mainly in the middle latitudes, where the prevailing westerlies generally move air from west to east. Jet streams are fast-moving currents of air high in the atmosphere that also steer weather systems and air masses across the country. Together, these patterns are the prevailing westerlies and jet streams, so choice A is correct.
