Which of the following requirement categories would be found in a requirements catalogue?

A Requirements Catalogue (or Requirements Specification) serves as the central repository for all documented requirements for a solution. BCS guidance categorises requirements hierarchically. At the highest level are the Business Requirements (often called General Requirements (c) and Technical Requirements (d)). These constrain the lower-level Solution Requirements, which consist of Functional Requirements (a) (what the system must do) and Non-functional Requirements (b) (quality attributes like performance, security, and usability). Since the catalogue aims to provide a complete picture of the business need and the proposed solution's capabilities, it must contain all four categories: Functional, Non-functional, General (Business), and Technical requirements.
