Explanation
The correct arrangement maps each REST principle to its definition based on the six core Fielding REST constraints: client-server separates UI concerns from data storage concerns; layered system means a client cannot tell whether it is connected directly to the end server or an intermediary; cacheable requires responses to define themselves as cacheable or non-cacheable to improve efficiency; stateless means each request from client to server must contain all information needed to understand the request, with no session state stored server-side; and uniform interface centralizes and decouples the architecture by applying a generalized interface between components. These definitions are foundational to RESTful API design and are directly tied to Roy Fielding's original dissertation constraints.
