The correct answer is: A. Ladaki Yak
Ladaki Yaks are a type of yak that are found in the Ladakh region of India. They are well-adapted to the cold and high altitude conditions of the region, and are used by the para-military forces patrolling in the border areas for their strength, endurance, and ability to carry heavy loads.
Dromedary camels are a type of camel that are found in the Middle East and North Africa. They are not as well-adapted to the cold and high altitude conditions of Ladakh as Ladaki Yaks, and are not used by the para-military forces patrolling in the border areas.
Equines are a group of animals that includes horses, donkeys, and mules. They are not as well-adapted to the cold and high altitude conditions of Ladakh as Ladaki Yaks, and are not used by the para-military forces patrolling in the border areas.
Zanskari Horses are a type of horse that are found in the Zanskar region of Ladakh. They are well-adapted to the cold and high altitude conditions of the region, but are not as strong or as able to carry heavy loads as Ladaki Yaks. Therefore, they are not used by the para-military forces patrolling in the border areas.
