Which of the following statements BEST describes the difference between testing and debugging?

The choice that states that dynamic testing shows failures caused by defects while debugging finds and removes the causes is the most accurate in articulating the distinction between testing and debugging.

Testing is primarily concerned with evaluating the software to discover issues, such as flaws or defects, during its execution. Dynamic testing involves executing the software in a runtime environment and identifying failures that occur due to these defects. This process helps determine whether the software behaves as expected under various conditions.

On the other hand, debugging is a more focused activity that takes place after a defect has been identified during testing. It involves analyzing the code and the conditions that led to a failure, identifying its root causes, and making the necessary corrections to resolve the issue. Essentially, debugging seeks to eliminate the exact reasons why a software failure occurred rather than simply highlighting that it happened.

This distinction emphasizes the complementary roles that testing and debugging play within the software development lifecycle, with testing identifying the presence of defects and debugging being the process to correct those defects effectively.
