The correct answer is C. taking care of sheeps and goats.
The Changpa tribe is a nomadic tribe that lives in the Changthang region of Ladakh, India. They are known for their expertise in sheep and goat herding. The entire family of Changpa tribe is involved in taking care of their livestock. They are responsible for grazing the animals, milking them, and shearing their wool. The Changpa also use their livestock for transportation and trade.
Agriculture is not a major activity for the Changpa tribe. The harsh climate of the Changthang region makes it difficult to grow crops. The Changpa do grow some barley and wheat, but they rely on their livestock for most of their food.
Hunting is also not a major activity for the Changpa tribe. The Changthang region is home to a variety of wildlife, but the Changpa do not hunt for food. They believe that hunting is disrespectful to the animals.
Therefore, the correct answer is C. taking care of sheeps and goats.
