A. Human beings are not allowed to enter.
B. People are an integral part of the system.
C. Plants are paid greater attention than animals.
D. Living organisms are brought from all over the world and preserved for posterity.

Answer 1

Hint :- A biosphere reserve is a particular land or marine protected area where all life types, including plants, insects, microbes, and humans, are conserved. In order to protect the species, national parks and wildlife sanctuaries are created and the biosphere is a global ecosystem made up of living creatures.

Complete answer:
First of all, only then you should distinguish the biosphere from national parks and wildlife sanctuaries, you should know what biosphere, national parks, and wildlife sanctuaries are. The biosphere is often referred to as the ecosphere that is the area of the earth's atmosphere and soil, or you might mean that it is a global ecosystem that consists of living organisms and the non-living factors on which energy and nutrients are obtained.
The National Park is an area that is designated for the protection of the natural environment by the government and its primary aim is to restore unique habitats and to maintain biodiversity. These parks are often designed for animal protection. In these parks, these species are safe. As part of education, people should also travel to these parks to explore and to learn about these parks.
In order to protect the endangered species from killing, trapping, and poaching them, wildlife sanctuaries are created. These are secured from disruption of some kind. To secure the remainder of their lives, animals are brought here to live. The primary goal is to provide animals with a healthy life. India has a magnificent sanctuary with birds, thick forests, and large waterways.
Biosphere reserves are insufficient without individuals and individuals to play an important role. In national parks and sanctuaries, there is limited human interaction. Humans are not an important part of them, then.

So the correct option is (b) i.e. People are an integral part of the system.

Note :- People play an integral part in the biosphere, but animals play an integral role in national parks and sanctuaries, and there is no point in doing that without them since they are created particularly for their safety and people do not play that essential role as they go to see nature as a museum.
