Red list contains data or information on
A. Threatened species
B. Marine vertebrates only
C. All economically important plants
D. Plants whose products are in international trade

Answer 1

Hint: The flora and fauna maintain the ecological balance of our nature so it becomes very important for us to save them from extinction. People are cutting down forests to use it commercially. So some land is reserved for the preservation of the wildlife as these lands provide them with their natural habitat.

Complete answer:
IUCN stands for International Union for Conservation of Nature. It is an organization which aims to protect nature and natural resources. It does the data gathering, projects, advocacy, research etc.
It has its headquarters in Switzerland. They adopted a Red list committee. This list includes the threatened species. There are approximately 85000 species of plants, animals and fungi.
Option A: Threatened species: These species are prone to get extinct or endangered in the future if not conserved today. They are enlisted in the Red list so that they can have greater help from society.
Option B: Marine vertebrates only: They include only the aquatic animals but the red list have all the land and water threatened species.
Option C: All economically important plants: Red list enlists all the plants, animals and fungi not only economically important plants.
Option D: Plants whose products are in international trade: The plants used in trade for economic purposes are exploited for man use but the red list includes all the animals and plants which are exploited and are threatened to be endangered.

So, the answer is option A: Threatened species

Note:
There are various national parks and national sanctuaries made. They protect the plants and animals from the endangered, threatened list. They are provided with all the nutrients and food to maintain the normal environment for them. They are free to move in their space.
