List of endangered species was released by

The correct option is IUCN.

Step-by-step Explanation:
1. Understanding IUCN: The International Union for Conservation of Nature (IUCN) is the global authority on the status of the natural world and the measures needed to safeguard it.
2. The Red List of Endangered Species: The IUCN compiles and publishes the IUCN Red List of Threatened Species (commonly known as the Red List). Established in 1964, it has evolved to become the world's most comprehensive information source on the global conservation status of animal, fungus, and plant species. It acts as a critical indicator of the health of the world’s biodiversity and is used to guide conservation actions and policy decisions.
3. Analyzing Other Options:
• GEAC (Genetic Engineering Appraisal Committee): An Indian regulatory body under the Ministry of Environment, Forest and Climate Change that assesses activities involving genetic engineering and GMOs.
• WWF (World Wide Fund for Nature): An international non-governmental organization focused on environmental conservation and reducing human impact on nature, but it does not compile or publish the official global endangered species list.
• FOAM (IFOAM - Organics International): An organization dedicated to the organic agriculture movement and standards, which has no role in listing threatened or endangered wild species.
