The correct answer is: B. Bawal
Slate stone is a type of sedimentary rock that is formed from mudstone or shale. It is a fine-grained rock that is typically black, gray, or green in color. Slate is a hard rock that is easily split into thin sheets. It is used in a variety of applications, including roofing, flooring, and countertops.
Bawal is a town in the Rewari district of Haryana, India. It is located about 100 kilometers from the state capital, Chandigarh. Bawal is a major industrial town and is known for its production of slate stone. The slate stone from Bawal is of high quality and is exported to many countries around the world.
The other options are incorrect because they are not places in the Rewari district where slate stone is found. Khol is a village in the Rewari district, but it is not known for its production of slate stone. Kund is a town in the Mahendragarh district, and Kosali is a village in the Jhajjar district. Neither Kund nor Kosali are known for their production of slate stone.
