The correct answer is option 2 - endangered category.

To understand this categorization, it is important to know that the International Union for Conservation of Nature (IUCN) is a global organization that evaluates the conservation status of species and assigns them to different categories. These categories reflect the level of threat a species faces in the wild.

The endangered category is used for species that are facing a very high risk of extinction in the wild. It indicates that the population size of the species has significantly declined, and if the current trends continue, it is likely to become extinct.

In the case of Red Sanders, also known as Red Sandalwood, it has been categorized as endangered by the IUCN. This means that the species is facing a high risk of extinction due to factors such as habitat loss, illegal logging, and overexploitation for its valuable wood. The categorization serves as a warning sign that urgent conservation efforts are needed to protect and recover the population of Red Sanders.
