The correct answer is D. Changthang area.
Pashmina goats are a type of goat that is found in the high-altitude regions of the Himalayas. They are known for their fine, soft wool, which is used to make pashmina shawls and other garments. The pastoral farming of pashmina goats is done in the Changthang area of Ladakh, India. This area is located at an altitude of over 4,000 meters (13,000 feet) and has a cold, dry climate. The pashmina goats are raised by nomadic herders who move their herds to different grazing areas throughout the year. The goats are sheared once a year, and their wool is then spun and woven into shawls and other garments. Pashmina shawls are highly prized for their beauty and warmth, and they are a popular tourist item in Ladakh.
The other options are incorrect because they are not areas where pashmina goats are raised. Shopian is a town in the Indian state of Jammu and Kashmir. Disket is a village in the Indian state of Himachal Pradesh. Khalsi is a village in the Indian state of Punjab.
