pseudocode, syntax, semantics, and logic.

A software design document typically covers the following areas:

Purpose, External Interface, Functional, and Non-Functional Requirements.

This section outlines the goal of the software, how it will interact with other systems or components (external interfaces), what functions it must be able to perform (functional requirements), and the criteria it must meet regarding performance, reliability, and other standards (non-functional requirements).

Other areas mentioned, like pseudocode, syntax, semantics, and logic, as well as data, architecture, interface, and procedural design, are also important aspects of software design but are usually more detailed than what a high-level design document tends to cover in its initial sections.

Each of the options provides valuable insights into different aspects of software design documentation, but the first choice is the most comprehensive in terms of essential content for understanding the overall design and requirements of the software project.
