Answer:
D. The Socialist Party.
Step-by-step explanation:
The Green Corn Rebellion was a revolt from the tenant-farmers in the state of Oklahoma during the early 20th century. It was a result of the farmers' long-standing displeasure/ discontent with the local landowners, authorities both local and state level, and wealthy businessmen.
The revolution was short-lived, ending with the death of three people. The revolt was primarily a result of the growing dissent of the tenants towards the wealthy landowners, businessmen, and authorities for the increasing land consolidation. This led to these tenant-farmers suffering badly, who comprise more than half of the farmer community in the state. Organized by the Socialist Party who had a large following and support, the failure of the rebellion led to the party getting discredited.
