The correct answer is B. The Great Famine affected Ireland in the mid-19th century as it led to a period of large-scale emigration out of Ireland.
Explanation:
The Great Famine was a period of starvation, disease and mass emigration in Ireland between 1845 and 1849. It is sometimes known, mostly outside Ireland, as the Irish potato famine, because approximately two fifths of the population depended exclusively from this cheap harvest 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%.
