Answer 1

The International Union for Conservation of Nature (IUCN; formally International Union for Conservation of Nature and Natural Resources) is a worldwide association working in the field of nature preservation and reasonable utilization of common resources. The International Union for the Conservation of Nature (IUCN) is the world's primary authority on the protection status of species.

Complete answer:
The IUCN Red List is set upon exact standards to assess the extinction risk of thousands of species and subspecies. These standards are relevant to all species and all districts of the world. The IUCN 'Red List of Threatened Species' is also called the IUCN Red List or 'Red Data List'. It was established in 1964, and it is the world's most extensive stock of the global conservation status of natural species.

A progression of 'Regional Red Lists' are created by nations or associations, which evaluate the danger of extinction to species within a political administration unit. The IUCN Red List is set upon exact measures to assess the elimination danger of thousands of species and subspecies.
These measures are relevant to all species and all areas of the world. The point is to pass on the desperation of protection issues to people in general and strategy creators, just as help the global community to attempt to decrease species extinction.

Hence, the correct answer is B, i.e. Endangered and Threatened.

Note: It is associated with data gathering and examination, research, field tasks, backing, and education. IUCN's main goal is to "impact, support and help social orders all through the world to conserve nature and to ensure that any utilization of natural resources is equitable and environmentally sustainable".
