Final answer:
The correct answer to which option is not a type of software requirement is B. Complexity. Complexity is a characteristic of software, not a requirement type. Similarly, for the review question on food security, the correct answer is D. Transformation, which isn't one of the four pillars of food security.
Step-by-step explanation:
The correct answer to the question is B. Complexity. In software development, requirements are specifications of what should be implemented. They are classified into various types such as functional, non-functional, performance, and external interface requirements.
Choices A (External Interface), C (Functionality), and D (Performance) are indeed types of software requirements. These categories describe the interactions with other systems, the capabilities the software should have, and the performance criteria the software must meet. However, Choice B (Complexity) is not considered a type of software requirement; rather, it is an attribute or characteristic that stems from the software's architecture and design.
Regarding the review question on food security, the correct answer is D. Transformation. The four pillars of food security are widely regarded as Availability, Access, Utilization, and Stability. These pillars represent the major areas that must be addressed to ensure food security for all. Transformation, on the other hand, does not fit within the accepted pillars of food security.
