Which statement about the Software Development Life Cycle (SDLC) is accurate?

• A. A software development life cycle with several phases.
• B. A data transmission protocol.
• C. A version control technique.
• D. A testing framework.

Answer: (A)

SDLC is a structured approach that describes the stages involved in building software from start to finish. The statement that it has several phases—requirements, design, implementation, testing, deployment, and maintenance—best captures how the process is organized to plan, build, verify, release, and support a system. This phased, lifecycle view helps teams coordinate work, manage risk, and ensure quality at each step. The other options describe tools or concepts that are part of the process but not the lifecycle itself: a data transmission protocol is about how data moves between systems; a version control technique focuses on tracking changes to code; and a testing framework is a toolset for running tests, which is just one activity within the SDLC rather than the overall lifecycle.
