(D) Stratosphere

Answer 1

Hint: In the above question, it is asked about the synonym of noosphere. The word “noo” is a Greek word which means mind and it is also known as sphere of reason.

Complete Step by step solution
Noosphere is defined as the sphere of reason. The conceptions of the noosphere share the common thesis that together human reason and scientific thought has created, and will continue to create, the next evolutionary geological layer.
The noosphere belongs to a family of concepts which describes planetary envelopes or domains that have shaped the earth’s history, that is, it describes envelopes like biosphere, hydrosphere, atmosphere, lithosphere, and so on. The idea of a distinct realm of mind evolved over several centuries. At first, French naturalist, Buffon, wrote of a realm of man that was beginning to transform the earth’s surface. Then other environmental thinkers such as George Perkins Marsh tried to measure the extent of those transformations, and Alexander von Humboldt declared that our impact on the planet was already incalculable.
The sphere of mind has evolved within the biosphere. All living organisms use their brain to control and coordinate the flow of energy and resources, so in other words we can say that the mind has always played an important role within the biosphere.
Hence, we can conclude that noosphere is the synonym of environment.
So, the correct option is option A.

Note
The sphere of mind had joined the planet-shaping spheres just over fifty years ago. In just a century or two, the noosphere has taken its place alongside the other great shapers of our planet’s history like cosmos, earth and life.
