The correct answer is Kutch.
Camels play an important role in the economy of Kutch, a region in the northwestern part of Gujarat. They are used for transportation, agriculture, and tourism. Camels are also a source of milk, meat, and wool.
Saurashtra is another region in Gujarat where camels are used for transportation and agriculture. However, they are not as important to the economy of Saurashtra as they are to the economy of Kutch.
North Gujarat is a region in the northern part of Gujarat. Camels are not as important to the economy of North Gujarat as they are to the economies of Kutch and Saurashtra.
South Gujarat is a region in the southern part of Gujarat. Camels are not used in South Gujarat.
