Where is the control for map text formatting located in ArcGIS Pro?

The control for map text formatting in ArcGIS Pro is found in the Labeling tab. This tab is specifically designed for managing how text is displayed on maps, allowing users to adjust font, size, style, and placement of labels using various options presented directly within it. The Labeling tab streamlines the process of configuring label properties for different layers, ensuring that users can efficiently and effectively control how text annotations appear on their maps.

In contrast, the other choices focus on different aspects of map design and data management. The Data tab is primarily used for managing data sources and their features rather than formatting text. The Appearance tab deals with overall visual properties of layers, such as colors and symbols, not specifically text formatting. The Symbology pane is tailored for configuring how features are symbolized on a map, which does not include label formatting options. Thus, the Labeling tab is the correct answer for controlling map text formatting.
