A biosphere reserve is divided into which three zones?
- A.Core, buffer and transition
- B.Core, sanctuary and park
- C.Inner, middle and outer
- D.Protected, restricted and open
Correct answer
Explanation
The correct answer is A, the core, buffer and transition zones. The core zone is legally protected and left undisturbed, with no human activity allowed. The buffer zone around it permits research, education and limited use of resources that does not damage the core. The transition zone is the outermost, where settlements, farming and other activities of local people carry on.
Option B mixes up two different kinds of protected area; a sanctuary and a national park are declared under the Wildlife (Protection) Act and are not zones of a biosphere reserve, although such areas often lie inside one. Options C and D are invented sets of names with no standing in the scheme. The three zone design is what allows a biosphere reserve to conserve strictly at the centre while letting people continue their livelihoods at the edge, which is why the model is described as conservation with development.
