The waterfall systems development approach follows a sequential structure in which one phase is substantially completed before the next begins. The expected flow is requirements definition, design, analysis or detailed specification, program design, coding, testing, and operation or maintenance. Among the available options, Option C presents the best sequence because it places requirements first, coding after design work, testing after coding, and operations last. Options A and D start with or place coding too early. Option B incorrectly places testing before coding. Internal audit should evaluate whether development projects have approved requirements, documented design, controlled coding, independent testing, user acceptance, and implementation approval. Therefore, Option C is the best answer from the options provided.
