Which of the following sections is the core of the IEEE 830 document?

The core of the IEEE 830 document is centered around the specific requirements. This section is crucial because it details all the functionalities, constraints, and performance criteria that the software product must meet. By clearly defining these specific requirements, the document provides a foundation for development and testing, ensuring that stakeholders have a shared understanding of what the software is expected to deliver.

The other sections, while important, serve a different purpose. Overall descriptions offer a high-level overview of the product and its context, product perspective situates the product within a larger system or operational environment, and product functions outline what the system should do in terms of tasks and behaviors. However, it is the specific requirements that are essential for guiding the design and implementation of the software, making it the core of the IEEE 830 document.
