Why should system artifacts be removed from applications?

The correct choice is based on the functionality of applications and the importance of data management within them. Removing system artifacts is crucial because they can hinder the ability of the application to export data effectively. System artifacts might include redundant or outdated files that don't contribute to the application's current processes. When these artifacts accumulate, they can create barriers to exporting clean, relevant data, which is essential for maintaining the integrity and performance of the application.

In contrast, unnecessary data or unsupported artifacts may affect system performance or compatibility but not specifically focus on the export functionality. Issues such as applications locking are more related to performance and stability rather than directly impacting the data export process. Therefore, ensuring that system artifacts are cleared can streamline operations and facilitate seamless data export, making it the most pertinent reason among the choices.
