Q1. Khus grass is mainly found in Rajasthan in:
Explanation
Khus grass, valued for its aromatic roots and soil-binding habit, is chiefly associated in Rajasthan with the Bharatpur and Tonk Forest Divisions. Western Rajasthan is dominated by arid-zone grasses and desert vegetation, so it is not the main answer for khus in this question. South-eastern Hadoti has a different vegetation profile with comparatively better rainfall, but the printed key links khus mainly to Bharatpur and Tonk. The Abu Mountain region has hill vegetation rather than the principal khus belt. Hence Bharatpur and Tonk Forest Divisions fit the question.
