All of the above

The correct answer is: d) All of the above.

Arunachal Pradesh is focusing on infrastructure development, capacity building of farmers, and value addition and processing to strengthen the livestock sector.

Infrastructure development includes the construction of new livestock markets, cold storage facilities, and veterinary hospitals. This will help to improve the quality of livestock products and make them more accessible to consumers.

Capacity building of farmers includes training them in modern livestock management practices and providing them with access to credit and other financial services. This will help farmers to increase their productivity and profitability.

Value addition and processing includes the development of new products from livestock, such as meat products, dairy products, and leather products. This will help to increase the value of livestock products and create new jobs in the livestock sector.

These measures are expected to help Arunachal Pradesh to achieve its goal of becoming a self-sufficient state in livestock production.
