In ArcGIS Pro, which tool is best for merging multiple datasets?

The Merge tool in ArcGIS Pro is specifically designed for combining multiple datasets into a single dataset. It allows you to take various input feature classes or tables and create one unified output feature class or table, which is particularly useful when you need to consolidate information from different sources for analysis or visualization. This functionality is essential for tasks such as data integration, where it's common to have multiple datasets representing similar types of information that need to be combined into one comprehensive dataset.

The other tools listed serve different purposes. The Buffer tool is used to create buffer zones around features, the Clip tool is intended to cut out portions of one dataset based on the boundaries of another, and the Intersect tool determines areas where multiple datasets overlap. Each of these tools has its own specific functions that do not involve merging datasets, making the Merge tool the most appropriate choice for the task at hand.
