Answer:
B. periodic movement
Explanation:
Migration consists of moving workers from their place of origin to other states / cities in order to pursue economic activities that will ensure an improvement in social and economic conditions.
Migration can be permanent when the worker moves to another location, or it can be a periodic movement when the worker makes the journey for a certain period and then returns home. If every year the peasants travel from the southwest to the east to gather apples, it means that they return to their homes again. Therefore, it is a periodic migratory movement.
