In ArcGIS, which tool is used to remove duplicate points from a dataset before analysis?

The correct choice is the Collect Events Tool. This tool is specifically designed to identify and group together coincident or overlapping points in a dataset, effectively removing duplicates before analysis. When working with spatial data, it is common to encounter multiple points that occupy the same geographic location. The Collect Events Tool consolidates these points into a single point, which can facilitate cleaner analysis and more accurate results.

In contrast, the Merge Tool combines multiple datasets into a single dataset but does not specifically address duplicate points within the same dataset. The Dissolve Tool is used to aggregate feature geometries based on specified attributes, which can eliminate duplicates when the features are similar based on those attributes, but it is not primarily aimed at point data. The Clip Tool is used to extract features that fall within a certain boundary, but it does not serve the purpose of removing duplicates from a dataset. Therefore, for the goal of removing duplicate points, the Collect Events Tool is the most appropriate choice.
