None of the statements is incorrect.

Sources of the seventeenth century refer to two kinds of peasants – khud-kashta and pahi-kashta. The former were residents of the village in which they held their lands. The latter were non-resident cultivators who belonged to some other village but cultivated lands elsewhere on a contractual basis. People became pahi-kashta either out of choice – for example when terms of revenue in a distant village were more favorable – or out of compulsion – for example, forced by economic distress after a famine.
