The correct answer is D. Irish.
Explanation
During the 1940s in Ireland, there was an episode known as the Great Famine caused by the loss of thousands of potato crops. On the other hand, at that time Ireland was a colony of the United Kingdom, so its lands were distributed among settlers who took advantage of this situation to appropriate the best lands. This situation worsened when a plague arrived that infected the potato crops that were the main source of food for the Irish so that there was not enough food for all the Irish so they had to emigrate about 1.5 million Irish to the United States, where they would have better opportunities for food and life in general. So, the correct answer is D. Irish.
