Answer 1

Hint: An endangered species is a species of those organisms that is likely to become extinct in the near future. These species are going extinct due to some factors such as habitat loss, poaching, invasive of other species, loss of environmental requirements and human activities.

Complete step by step answer:
-A word ‘Red’ indicates those threatened species or species which are under various degrees of extinction or at a risk to become extinct.
-It is the compliance of data on species threatened with extinction and is maintained by IUCN.
-The existence of various species of plants and animals is threatened, so there is a need to list all those endangered species. Endangered species means that all these plants and animals are present in a lesser number.
-The names of the species are noted down in this book with other details as a record.
-In India, Red data books contain detailed information of animals and plants that are endemic to India and its neighboring countries as well.
-In this book the extinction risk of species and subspecies is showed in the sheets in the form of color coded information as follows-
-Red sheets contain all the information of those species which are rare.
-Black sheet contains information about the species which are confirmed to be extinct.
-White sheet contains information of those species which are rare.
-Green sheet is arranged for those species which are formally endangered but now starting to recover.
Hence, the correct option is (C) Red data book.

Note:
-IUCN i.e., International Union for Conservation of Nature and Natural Resources. It is an international organisation that maintains a red data book or red list. It is in the form of a catalogue of taxonomic groups that are at the verge of extinction.
-In India, ZSI (zoological survey of India) and BSI (botanical survey of India) maintains a Red Data Book.
