The correct answer is A) Central Asia.
Prior to the destruction of the second temple, the areas of the world that contained Diaspora Communities was Central Asia.
The Diaspora was notoriously increased after the Roman destruction of the Second Temple of Salomon in Jerusalem in 70 CE. Then, Jewish people scattered all over Central Asia and went beyond, to Europe and some parts of North Africa. For years, Jewish people traveled around many countries in different Diasporas until they finally were granted the land of Israel in the Arab territory.
