Suggested answer: D

Explanation:

Component integration testing is the process of testing the interactions between different components of a system. It should always be done before system testing, which is the process of testing the system as a whole. Integration testing can reveal defects in the interfaces and interactions between components, which can affect the functionality and performance of the system. System testing can reveal defects in the system requirements, design, and behavior, which can affect the quality and usability of the system. Therefore, it is logical to perform integration testing before system testing, to ensure that the components work together correctly before testing the system as a whole.
