Answer:
B. Vertical mobility.
Step-by-step explanation:
In vertical mobility, you move up or down in the hierarchy of a certain field or any kind. For example, a factory worker who enrolls in college and becomes an international businessman. Therefore, vertical mobility refers to a person or group's movement up or down a status hierarchy. As many people know, in Arab countries there was a very strong sexist community and women could not perform many tasks apart from the household chores, and now we can see through this example how women are taking higher positions and being valued for what they have studied or learned and the community is leaving behind gender discrimination little by little.
