Hint: The color 'Red' stands for Danger. Also, we know that some species or organisms are on the verge of being endangered.
Complete step by step answer:
The Red Data Book is a book that contains or documents the rare and endangered species of animals, plants, and fungi. It is a complete list of such species. It provides information for studying species that are endangered and for their research. The species are classified into different categories which are arranged according to extinction risk of the species.
The categories mentioned in the Red Data Book are,
- Black: Species confirmed to be extinct
- Red: Endangered species
- Amber: species which are considered to be vulnerable
- White: Rare species
- Green: Species which are endangered but they are recovering
- Grey: Species for which proper information is unavailable to put them in the above-mentioned categories.
So, the correct answer to the above question is, D. Threatened species.
Additional Information:
There is an International Union for Conservation of Nature which is responsible for maintaining the Red Data Book. It aims to maintain a complete record of all the species that have existed in the world. It was founded in 1948 and has been in full functioning since then.
Note: We all usually get confused between vulnerable, endangered, and threatened species. To avoid this, we must remember,
Vulnerable species are those that are currently at the risk of being endangered.
Endangered species are those which are at the risk of becoming extinct.
Extinct species are those which no longer exist and cannot be recovered now at all.
