Which statement accurately describes system non-functional requirements and their role in software behavior?

Procedures for application retirement or decommissioning are typically part of operational processes or system lifecycle management, not core non-functional requirements that define software behavior.

While an application's behavior during outages (e.g., resilience, fault tolerance) falls under non-functional requirements, this choice is too narrow and specific compared to the comprehensive definition of NFRs.

Non-functional requirements (NFRs) specify criteria that can be used to judge the operation of a system, rather than specific behaviors or functions. They describe how the system should perform, encompassing quality attributes like performance (e.g., response time), scalability (e.g., user capacity), security (e.g., authentication, authorization), usability (e.g., ease of use), and maintainability (e.g., ease of modification).

While platform controls like Cloud IAM and firewall rules help satisfy certain security non-functional requirements, NFRs are the definition of those requirements, not the implementation mechanisms themselves.
