Question

british landownership changed irish society by
doing away with all farms.
establishing cotton plantations.
forcing farmers to grow cash crops.
importing enslaved people to work on plantations.

Explanation:

British landowners in Ireland shifted agricultural production away from subsistence farming, compelling tenant farmers to grow cash crops for export to Britain, which disrupted traditional Irish rural life and food security. The other options are incorrect: farms were not eliminated, cotton plantations were not a feature of Irish agriculture under British landowners, and enslaved people were not imported to work in Ireland.

Answer:

forcing farmers to grow cash crops.
