Generally, environment can be classified as following categories. Which among the following is NOT a part of such category?

The correct answer is A. Operational Environment is not one of the standard categories used to classify the environment.

The usual three-fold classification is:

• Physical environment: the non-living natural setting, such as land, water, air, climate and soil. The Environment (Protection) Act, 1986 defines environment in these terms, covering water, air and land.
• Biological environment: all living components, including flora, fauna, microorganisms and humans as part of the ecosystem.
• Cultural environment: the man-made social setting, including customs, values, institutions, language, technology and economic systems.

Operational environment is a term from organisational management. It refers to a firm's immediate task environment, such as suppliers, customers and competitors. It belongs to business studies, not to the general classification of the environment.

Mains angle: the cultural environment is the link to heritage conservation, social change and the human side of development projects, which often decide how an EIA or a welfare scheme actually works on the ground.

Trap: aspirants often read "environment" as only ecology and then get confused by the cultural category. Others see "operational" and assume it is a valid environmental category just because it sounds like a management term.
