To visualize population change, the attribute (change in population) must be accessible to the county feature layer’s symbology engine. A Join operation adds the table fields directly to the feature layer’s attribute table based on a common key (county field), making the data available for symbology classification.

Relate creates a temporary relationship but does not merge data for symbology purposes.

Spatial Join is used when spatial relationships are needed; here, the relationship is attribute-based.

Join correctly allows the standalone table values to drive symbology on the spatial features.

Therefore, the correct answer is B.

ArcGIS Pro’sMatrix Heat Chartis designed for visualizing relationships between two categorical fields—such as origin and destination cities—and summarizing a numeric field, like delay time, using aggregate functions (e.g., mean). This type of chart aligns perfectly with the requirement:

It allows you to setColumnto the destination city andRowto the origin city.

Then choose theNumberfield as delay time and theAggregationmethod as "Mean" to calculate average delay.

The chart displays each origin‑destination pair as a cell, color‑coded by the calculated average delay.

Official documentation highlights this example explicitly:

“Create a matrix heat chart to identify the flights that have the highest average arrival delay time between origin and destination city by setting the following properties… Aggregation—Mean; Number—DelayTime”

Other chart types don’t fit the requirement:

Box plotis used to display distributions and identify outliers; it doesn’t aggregate by category pairs.

Scatter plotshows relationships between numeric variables on a continuous axis—not suitable for categorical city‑pair aggregation.

Therefore, the most appropriate choice for summarizing average journey delay by city pairs is theMatrix Heat Chart (C).

Visibility range (also called scale range) controls at what zoom levels a layer or features are displayed. This allows the map to automatically hide features when zoomed out too far, improving performance and reducing clutter, while showing detailed features as the user zooms in.

Definition query (Option A) filters features based on attribute values, not map scale.

Display filters (Option C) filter features at specific scales but require advanced configuration; visibility range is more direct for simple scale-based drawing control.

Therefore, the correct answer is B.
