A GIS analyst is trying to buffer single point features one at a time within...

The Multipart To Singlepart tool separates multipart features into individual single-part features. This ensures that when selecting a feature, only the intended single feature is selected, rather than selecting multiple points grouped in a multipart feature.

Explode (Option A) is not a valid geoprocessing tool for this scenario.

Split (Option C) is used for dividing features, not separating multipart features.

Therefore, the correct answer is B.
