Answer:a) culture shock
Explanation:
This occurs when someone is away from the country of theirs and they get exposed to cultural behaviours or loving with which they are not familiar.
It takes time for a person to get used to these ideas of living that they find in a foreign country evethough it may be normal or a norm for people of that country but being unfamiliar with them as a foreign citizen one will be very shocked.
For example in this text people of Saudi Arabia are used to how women are treated as compared to men because for them it is part of their religion and it is a norm in their culture , it is how they have been raised .
