The correct answer is: A. Ibex.
Hemis National Park is a protected area in the Ladakh region of India. It is home to a variety of wildlife, including ibex, hangul, snow leopards, and black bears. However, ibex are the most abundant species in the park, with an estimated population of over 10,000. Ibex are wild goats that are well-adapted to the high-altitude environment of the Himalayas. They are herbivores and their diet consists mainly of grasses, herbs, and shrubs. Ibex are social animals and live in herds of up to 50 individuals. They are an important part of the ecosystem of Hemis National Park and play a role in seed dispersal and grazing.
Hangul are a type of deer that are also found in Hemis National Park. They are smaller than ibex and have a reddish-brown coat. Hangul are shy and elusive animals and are difficult to spot. They are an endangered species and their population is estimated to be around 2,500 individuals. Snow leopards are the rarest animals in Hemis National Park. They are large cats that are adapted to living in the cold climate of the Himalayas. Snow leopards are solitary animals and their diet consists mainly of wild goats, sheep, and hares. They are an endangered species and their population is estimated to be around 4,000 individuals. Black bears are the only bears found in Hemis National Park. They are large, omnivorous animals that are found in a variety of habitats, including forests, mountains, and grasslands. Black bears are not endangered but their population is declining due to habitat loss and hunting.
