The correct answer is: d) All of the above.
One-horned rhinoceroses are critically endangered, with only about 3,500 individuals remaining in the wild. The main threats to their survival are habitat loss, poaching, and conflict with humans.
Conservation efforts for the one-horned rhinoceros in Assam need to address all of these threats. Providing adequate food sources during floods is important because rhinos are large animals that need a lot of food to survive. Floods can destroy their food sources, so it is important to provide them with alternative sources of food during these times.
Creating elevated shelters for protection is also important because rhinos are vulnerable to poaching and other threats. Elevated shelters can provide them with a safe place to hide from predators and poachers.
Managing habitat restoration is also important because rhinos need a healthy habitat to survive. Habitat loss is one of the main threats to their survival, so it is important to restore and protect their habitat.
All of these conservation efforts are essential for the survival of the one-horned rhinoceros in Assam.
