Which statement about open systems is true?

Which statement about open systems is true?

• A. It isolates from the environment
• B. It never uses feedback
• C. It avoids change
• D. It continually interacts with the environment

Answer: (D)

Open systems are defined by their ongoing exchange with the external world—energy, materials, and information flow across their boundaries. Because of these exchanges, they are not isolated and must continually respond to inputs and disturbances from the environment. Feedback loops are central here: they provide information about how well the system is functioning and what adjustments are needed. This makes adaptation and change a natural part of an open system’s behavior. So, the statement that open systems continually interact with the environment is true. The other options conflict with this view: an open system is not isolated from its surroundings; it uses feedback to regulate and improve performance; and it does not avoid change—adapting to new inputs is inherent to its operation.
