The correct answer is B. Diaspora
Step-by-step explanation:
The word "diaspora" refers to the process of scattering a specific group from a territory they are supposed to own or belong to, this term is used in the case of Jews that claimed to be scattered from their homeland (Israel). But the term has been used in many other cases such as the process of slavery in Africa that took Africans to America which force them to leave their original homeland or the massive migration of the Irish population during the historical period known as Great Famine. In all these cases, the migration or scattering of population concerns a specific ethnic or group and occurs as they are forced to live their territory. Therefore, it is diaspora the term that matches the definition "a scattering of an ethnic population from its original homeland".
