c. Irish

Explanation:

During the 1800's, the largest group of immigrants that came into the United States were the Irish people. The reason for that was a tragedy that happened in Ireland, the Potato Famine. The Potato Famine in Ireland was so bad, that the majority of the population was barely surviving from day to day, large percentage of the population died for starvation, and the economy suffered very badly because of it. The uncertainty about having a meal on the table, made lot of Irish people to migrate. The US opened up its borders to help them, and changed the conditions for immigration just because of the Irish people. The Irish moved in the US, and the US showed big heart in helping over 1.5 million people in this terrible humanitarian crisis.
