What is the difference between the antelopes Oryx and Chiru?

Result
Your answer: —  Â·  Correct: A
Explanation

The primary difference between the two antelopes lies in their habitat adaptations. Oryx species, such as the Arabian oryx and gemsbok, are adapted to hot and arid near-desert conditions in Africa and the Arabian Peninsula, where they can survive without water for long periods [4]. In contrast, the Chiru (Tibetan Antelope) is adapted to the cold, high-altitude environments of the Tibetan plateau and the cold deserts of Ladakh and Himachal Pradesh, typically inhabiting steppes and semi-desert areas [3]. Regarding other options, the Chiru is poached for its fine 'shahtoosh' wool rather than musk [1]. While the Chiru is found in the cold deserts of northern India (Ladakh), the Oryx is not native to India; the Indian antelope mentioned in similar arid contexts is the Black-buck or Chinkara [1].
