The correct answer is Option (4) → So that it might recover its strength

Option (1) Because its cultivators had moved to colonise new lands — Incorrect. Zamindars did colonise new lands with settled cultivators. The Ain links parauti only to resting the land for a time.

Option (2) So that it might serve as grazing ground for village cattle — Incorrect. The Ain describes parauti as land left out of cultivation for a time so that it may recover its strength; grazing has no place in that classification.

Option (3) Until revenue officials could measure and classify it — Incorrect. Parauti was already one of the Ain's classes of land with a fixed revenue, like polaj; it was left fallow so that it might recover its strength.

Option (4) So that it might recover its strength — Correct. <strong>Parauti</strong> land was rested on purpose <strong>so that it may recover its strength</strong>. Polaj, by contrast, was never allowed to lie fallow.
