• A. i & ii
• B. ii & iii
• C. iii & iv
• D. i & iv

Answer 1

The correct option is C

iii & iv

The correct option is C.

Explanation of the correct option:

1. Red data book keeps a record of all the endangered plants and animals or the species which are at continuous threat of becoming extinct.
2. There are various colour codes for various types of species depending on the level of risk they are in when it comes to becoming extinct.
3. Depending on the records present in the red data book necessary steps are taken to protect the endangered species.

Explanation of the incorrect options:

Option A:

1. Endemic species are those species that are found in a particular area only.
2. Having a record of those species in the red book isn’t necessary as it doesn’t help us to increase the number of species as a whole worldwide.
3. Extinct species are the species that are already extinct and whose population is rarely seen anywhere around.
4. As the red data book gives us an overall view of the number of species that are in danger having the records of endemic or extinct species is of no use in it.

Option B:

1. Red data book keeps a record of all the endangered plants.
2. Depending on the records present in the red data book, necessary steps are taken to protect the endangered species.
3. However extinct species are the species that are already extinct and whose population is rarely seen anywhere around so having their record is not going to increase their population.

Option D:

1. Endemic species are those species that are found in a particular area only.
2. Having a record of those species in the red book isn’t necessary as it doesn’t help us to increase the number of species as a whole worldwide.
3. However endangered animals are those species that are on the verge of being extinct so having their records in the red data book might help us in increasing their number worldwide.

Final answer: The Red Data Book keeps a record of all the (iii) endangered plants (iv) endangered animals.
