Chabro is a variety of …………… given to farmers in Himachal Pradesh to sustain their income.

The correct answer is: B. Yak

Chabro is a variety of yak given to farmers in Himachal Pradesh to sustain their income. Yaks are hardy animals that can survive in the cold climate of the Himalayas. They are also good at carrying heavy loads, which makes them ideal for transporting goods in the mountains. Yaks are also a source of milk, meat, and wool for the farmers.

The other options are incorrect because:

• Horses are not a major source of income for farmers in Himachal Pradesh.
• Poultry is not a good option for farmers in Himachal Pradesh because the climate is not ideal for raising chickens.
• Cows are not as hardy as yaks and are not as well-suited to the cold climate of the Himalayas.
