Answer:
C.Huge numbers of Irish people emigrated to Canada and the United States.
Step-by-step explanation:
The Great Famine or Great Hunger was a period of starvation, disease and mass emigration in Ireland between 1845 and 1849. It is sometimes known, mostly outside of Ireland, as the Irish potato famine, because about two fifths of the population depended exclusively on this cheap crop for a number of historical reasons. During the famine, around one million people died and a million more emigrated from Ireland, causing the population of the island to fall between 20% and 25%.
