Final answer:
The correct answer for portability in non-functional requirements is that it describes the ease of transferring software across different platforms. To enhance portability, standardized tools and languages can be used. Transformation is not one of the four pillars of food security; they are Availability, Access, Utilization, and Stability.
Step-by-step explanation:
The statement that explains portability in non-functional requirements is: It is a degree to which software running on one platform can easily be converted to run on another platform. Portability refers to the ease with which software can be transferred from one environment to another. This could be between different types of hardware, operating systems, or software environments. Enhancing portability often involves using programming languages, operating systems, and tools that are universally available and standardized, contrary to the claim that portability cannot be enhanced by these means.
Now, for the review question about food security, the correct answer is: D. Transformation. The four pillars of food security are Availability, Access, Utilization, and Stability. These represent the widely accepted framework for understanding and addressing food security issues.
