To answer this question, you need to understand the concepts of top-down integration and bottom-up integration.
Option A) Top-down integration - This option is incorrect because top-down integration starts with the highest-level modules and gradually integrates lower-level modules.
Option B) Bottom-up integration - This option is correct because bottom-up integration starts with the terminal modules (i.e., the lowest-level modules) and gradually integrates higher-level modules.
Option C) None of the above - This option is incorrect because one of the given options is correct.
Option D) Module integration - This option is incorrect because it does not accurately describe the process starting with the terminal modules.
The correct answer is Option B) Bottom-up integration. This option is correct because it accurately describes the process starting with the terminal modules and gradually integrating higher-level modules.
