Answer:
Option (D)
Step-by-step explanation:

The polar easterlies are defined as the cold and dry wind that blows from the high pressure polar areas towards the low pressure areas in both the hemisphere. These polar easterlies and westerlies meets at the low pressure zone forming the sub-polar low areas.
Thus, the correct answer is option (D).
