The correct answer is C. Landowning class.
The Jenmi system was a feudal system in Kerala, India, in which the Jenmi (landlord) class owned most of the land and the lower classes were tenants who worked the land for the Jenmi. The Jenmi system was abolished in 1970.
Temple priests, subordinate rulers, and tribal chieftains were all important figures in Kerala, but they did not own land under the Jenmi system.
Temple priests were responsible for the upkeep of temples and the performance of religious ceremonies. Subordinate rulers were appointed by the king to govern provinces or districts. Tribal chieftains were leaders of indigenous peoples who lived in remote areas of Kerala.
