Regression testing plays a crucial role in ensuring the integrity and reliability of a software application as it undergoes updates and modifications. The primary significance of regression testing is to verify that new changes, such as bug fixes or feature enhancements, have not adversely affected the existing functionalities of the software.

By rigorously testing the previously developed and tested features after changes have been made, regression testing helps to identify any unexpected issues that may arise as a result of these changes. This process minimizes the risk of introducing new errors into a system that was previously functioning well, thereby safeguarding the quality of the software and ensuring a smooth user experience.

In contrast, other options present activities that do not directly relate to the core purpose of regression testing. For example, not adding new features before deployment relates more to project management or release planning, while gathering feedback from end-users focuses on usability and user experience rather than functional integrity. Load testing assesses how the system performs under varying loads, which is distinct from verifying existing functionalities. Thus, regression testing specifically targets the preservation of existing functional quality after changes are made.
