B) List of water pollutants
C) List of threatened species
D) Rate of population decline

Answer 1

The name of this book originated in Russia and was originally referred to as the Russian Federation's Red Data Book, or RDBRF. The book was based on research by biologists in Russia conducted between 1961 and 1964. Hence, it is often referred to as the Red Data Book of Russia.

Complete answer:
The Red Data Book is a public document for the purpose of tracking endangered and rare species of plants, animals, fungi and some local subspecies found in a particular field.

The Red Data Book allows us to provide full information on rare and endangered species and their habitats for research, analysis and monitoring programmes.
The main aim of this book is to recognise and conserve certain species that are on the verge of extinction.

The entire list of endangered species is contained in the Red Data Book. The main purpose behind this documentation is to provide detailed information for the study and review of various organisms.
The Red Data Book contains information sheets which according to the likelihood of extinction of many species and subspecies, are colour-coded and arranged.

-Black describes animals that are proven to be extinct.
-Red reflects endangered species,
-For those species whose status is considered vulnerable, amber
-For species that are rare, White is assigned
-Green for species that were once endangered, but have begun to regain their numbers
-There is insufficient information available for species that are listed as vulnerable, threatened, or rare but adequate to be properly classified.

The Red Data Book, in a nutshell, indexes species as
-Being endangered
-Not endangered
-Unknown

The Red Data Book also has details on whether a species, along with population patterns and the extent of its range, has become extinct (distribution).

The correct answer is option (C) i.e, List of threatened species.

Note: The conservation status of animals and plants which are native to the Indian subcontinent is protected by the Red Data Book of India. The data for this book is provided by surveys conducted under the guidance of the Ministry of Environment, Forests and Climate Change by the Zoological Survey of India and the Botanical Survey of India.
