The correct answer is: A. Khol
Khol is a village in the Rewari district of Haryana, India. It is located about 15 kilometers from the district headquarters of Rewari. The village is known for its huge reserves of slate. Slate is a type of sedimentary rock that is used in a variety of applications, including roofing, flooring, and countertops. The slate from Khol is considered to be of high quality and is in demand by both domestic and international buyers.
The other options are incorrect because they are not villages in the Rewari district of Haryana. Bayal is a village in the Jhajjar district of Haryana, Kund is a village in the Mahendragarh district of Haryana, and Kosli is a town in the Rewari district of Haryana.
