Final answer:
In the open systems perspective, 'C. Environment' would be considered an input as it is the source of resources for the system. Inputs are then processed through throughput to generate outputs, while feedback affects future inputs and internal processes.
Step-by-step explanation:
According to the open systems perspective, an organization is viewed as an open system that interacts with its environment. In this context, inputs are the resources or elements that are taken from the environment into the system to be processed and converted into outputs. Therefore, among the options provided, the answer would be "C. Environment" as the source of inputs for the system.
Inputs in open systems can include raw materials, information, human resources, and energy, which are then subjected to throughput processes within the organization. The results of these processes are the outputs, which include products, services, waste, and byproducts that the system releases back into the environment. An important aspect of the open system is the feedback mechanism, which is information about the output that is returned to the system, influencing future inputs and processes.
