Requirement Analysis Phase

D.

Security requirements should be incorporated into the software development lifecycle (SDLC) from the earliest requirement gathering stage and should be incorporated prior to the requirement analysis phase.

The requirement analysis phase of the software development lifecycle is a critical step in determining what the software should do, how it should do it, and what features it should have. During this phase, developers work with stakeholders to gather and analyze requirements for the software project.

Out of the options given, programming languages and software platforms are technical considerations that are typically evaluated during the design and implementation phases of the software development lifecycle. As such, they would not typically be included in the requirement analysis phase.

Functionality and security requirements, on the other hand, are critical components of the requirement analysis phase. The functionality requirements define what the software needs to do, while security requirements define how it needs to do it securely. Both of these requirements are essential in determining the scope of the project, the level of effort required, and the potential risks associated with the software.

Therefore, the correct answer to the question is B. Programming languages, as it is not typically included in the requirement analysis phase of the software development lifecycle.
