Answer: A. A closed loop system responds to changes in the environment

Explanation: The correct answer is “A. A closed loop system responds to changes in the environment”. A closed loop system is designed to maintain control without relying on external environmental inputs, instead, it uses feedback from within the system itself. It does not actively adapt to external changes but adjusts its internal behavior based on internal feedback.

Run down: Closed loop systems use feedback to maintain desired system behavior, typically in automation and control processes. They are self-regulating, as opposed to open loop systems, which require external inputs to operate.
