Which of the following is a structure-based (white-box) technique?

Statement testing is a structure-based (white-box) technique. This technique involves testing the internal structure of the application, focusing on the execution of the statements within the code. The goal is to ensure that every statement in the code has been executed at least once during the testing process. Other options like decision table testing, state transition testing, and boundary value analysis are black-box techniques, which do not require knowledge of the internal code structure.
