What is a benefit of using a Lookup Filter instead of a Validation Rule?

Using a Lookup Filter provides the benefit of improving user efficiency when selecting a related record because it streamlines the process of finding the correct record in a lookup field. A Lookup Filter allows users to see only those records that meet specified criteria, making it easier to locate and select the relevant data without having to sift through a potentially large number of unrelated entries. This targeted approach reduces confusion and saves time, enhancing the overall user experience.

While other options relate to features that are beneficial in certain contexts, they do not directly address the specific efficiency gains offered by a Lookup Filter in the context of record selection.
