Q.The one-horned rhinoceros is specific to which of the following sanctuary

The one-horned rhinoceros (Rhinoceros unicornis) is a flagship species of the Indian subcontinent and has become critically endangered due to habitat loss and poaching. Its survival depends on well-protected wetland and grassland ecosystems.

Kaziranga National Park in Assam is the primary stronghold for this species. The park's floodplains, tall elephant grass, and swampy terrain provide ideal habitat, and it harbors the largest population of one-horned rhinos in the world. Kaziranga was specifically established to protect this species after its numbers plummeted in the early 20th century.

The other options do not support one-horned rhino populations:

• Bhitar Kanika (Odisha) is a mangrove sanctuary known for saltwater crocodiles and nesting sea turtles. …

The one-horned rhinoceros, also called the Indian rhinoceros (Rhinoceros unicornis), is one of the most iconic and endangered large mammals of the Indian subcontinent. Understanding where this species survives tells us a great deal about habitat conservation and the success of wildlife protection efforts in India.

Kaziranga National Park in Assam is the primary and most significant sanctuary for the one-horned rhinoceros. Located in the floodplains of the Brahmaputra River, Kaziranga provides the tall grasslands and wetland ecosystems that this species needs. The park holds the largest population of one-horned rhinos in the world — a conservation success story that has brought the species back from the brink of extinction. The combination of riverine habitat, swamps, and grasslands creates the perfect environment for these massive herbivores, which feed on grasses, reeds, and aquatic plants.

Let's briefly consider why the other options don't fit:

• Bhitar Kanika (Odisha) is a mangrove sanctuary famous for saltwater crocodiles and nesting Olive Ridley turtles, not rhinoceros habitat.
• Bandipur (Karnataka) is a dry deciduous forest reserve known for elephants, tigers, and gaur — the landscape is entirely different from what rhinos require.
• Corbett National Park (Uttarakhand), India's oldest national park, is celebrated for its Bengal tigers and is located in the Himalayan foothills with sal forests and grasslands, but it is not a rhino habitat. …

Match the species to its specific habitat requirement, not just 'a wildlife park in India': the one-horned rhino needs river floodplain grassland and swamp, a habitat type only Kaziranga (Brahmaputra floodplain, Assam) offers among the four options — Bhitar Kanika is mangrove/coastal, Bandipu …
