Explanation

The iqta was the Delhi Sultanate's system of assigning the land revenue of a territorial unit to military officers and nobles (muqtis or walis) in lieu of cash salaries, in return for military service. It was not a religious endowment (that would be waqf or inam), nor charity for education, nor the hereditary rights of zamindars, who were a different, later category of revenue intermediaries. The correct meaning is the revenue assignment to army officers, option (B).
