Explanation:

The Irish Potato Famine occurred because farmers relied heavily on a single potato variety (the Lumper) which was susceptible to the potato blight (Phytophthora infestans). Option A correctly states that farmers planted the same variety susceptible to blight. Option B is incorrect as they didn't plant infected potatoes initially, the blight infected them. Option C is wrong as they planted enough but the blight destroyed the crop. Option D is incorrect as potatoes can be a staple crop (they were in Ireland).

Answer:

A. The farmers all planted the same potato variety, which was susceptible to a potato blight.
