The 'Red Data Book' containing information on all wild paints and animals in danger of extinction has been published by which one of the following ?

The 'Red Data Book' is a comprehensive inventory of the global conservation status and extinction risk of biological species, including both plants and animals [c1][t5]. It was first issued in 1966 by the International Union for Conservation of Nature (IUCN), specifically through its Species Survival Commission [c1][c2]. The IUCN, also known as the International Union for Conservation of Nature and Natural Resources, is the global authority on the status of the natural world [t1][t3]. While the organization was previously referred to as the World Conservation Union (WCU) in some contexts, the primary and official publisher remains the IUCN [c1][t4]. The book provides critical information on species' range, population size, and threats, categorizing them into groups such as 'Critically Endangered' or 'Endangered' to catalyze conservation action and policy change [t4][t9].
