Which of the following provides a benefit of safety in Alteryx designer?

The choice that highlights a significant benefit of safety in Alteryx Designer is ensuring only authorized users can access data. This feature is crucial for data security and compliance, as it helps to protect sensitive information from unauthorized access or breaches. By implementing user permissions and access controls, organizations can safeguard their data assets, ensuring that only those who are authorized can manipulate or view data within the system. This level of security is essential for maintaining the integrity and confidentiality of data, particularly in environments that handle sensitive information or are subject to regulatory scrutiny.

While the other options do contribute to usability and functionality within Alteryx Designer, they do not directly address the concept of safety in terms of protecting data access. Clear documentation of workflows enhances understanding and collaboration, undoing changes aids in error correction, and real-time validations help ensure accuracy and reliability, but these elements do not specifically focus on access control and safeguarding sensitive data from unauthorized users.
