Correct Option
The Oryx (Oryx gazella) is an antelope species adapted to hot and arid environments, such as deserts and semi-desert regions, primarily found in Africa and historically in parts of Western India. In contrast, the Chiru (Pantholops hodgsonii), also known as the Tibetan Antelope, is adapted to live in the cold, high-altitude steppes and semi-desert areas of the Tibetan Plateau and the Ladakh region of India. This distinction in their ecological adaptations to vastly different climatic conditions is a key difference.
Incorrect Options
Option 2 is incorrect. The Chiru is primarily poached for its exceptionally fine underfur, known as Shahtoosh wool, which is used to make luxurious shawls, not for its musk. Oryx species are generally not targeted for their antlers; they face threats from habitat loss and hunting for meat.
Option 3 is incorrect. Oryx species have a broader distribution, predominantly across Africa and the Arabian Peninsula, with some populations historically present in parts of Western India. The Chiru is found in the high-altitude regions of the Tibetan Plateau, which includes the Ladakh region in North-West India, not North-East India.
