Here, the organisation can be seen as either an . . . . . . . . where it interacts with its external environment or a . . . . . . . . system where it has no interaction with its external environment.

The correct answer is: C. open, closed

An open system is a system that interacts with its environment. It takes in resources from the environment and produces outputs that are returned to the environment. An open system is constantly changing and adapting to its environment.

A closed system is a system that does not interact with its environment. It does not take in resources from the environment and does not produce outputs that are returned to the environment. A closed system is not constantly changing and adapting to its environment.

In the context of the question, the organization can be seen as either an open system or a closed system. An open system would be one that interacts with its external environment, such as by taking in resources from customers or suppliers, or by producing outputs that are returned to the environment, such as pollution or waste. A closed system would be one that does not interact with its external environment, such as a self-contained computer system.

The correct answer is C because the organization is described as interacting with its external environment. This means that it is an open system.
