D Correct answer
Explanation

Nonfunctional criteria (also called quality attributes) describe how a system behaves rather than what it does. Availability is a classic nonfunctional requirement specifying the percentage of time a system must be operational. Requirements (A), specifications (E), and failure modes (C) are functional or process-related, while defect density (B) is a quality metric rather than a requirement type.
