The correct answer is - C. Israel.
Prior to the Diaspora, Israel, or rather Judah in that period of time, had already been captured by the armies of the Assyrians and the Babylonians. Even though Judah (Israel) was a vassal of the aforementioned Assyrians, and the kingdom payed its annual share of tribute to the Assyrian Empire, in the year of 721 BC, it was attacked and captured by the Assyrian armies.
Once the territory of the Israelite people was captured, the Assyrians carried away this people into captivity, and also forced them out of their homeland, which made the Israelite people to spread in the territories of the northern coast of Africa and the areas of the Eastern Mediterranean.
The Assyrians did this because the Kingdom of Israel was the only country between them and Egypt, and they wanted to have full control of the situation, as well as having a better position to attack them.
