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).

Versioning allows multiple editors to work simultaneously on the same dataset in an enterprise geodatabase without interfering with each other or encountering schema locks. Each editor works on a separate version, and changes can later be reconciled and posted.

Archiving (Option A) tracks historical edits but does not address schema locks.

Editor tracking (Option C) records who made changes and when, but does not resolve simultaneous editing conflicts.

Therefore, the correct answer is B.

In ArcGIS Pro, ared Xnext to a parameter in a geoprocessing tool typically indicates an invalid input due to conflicts with the current environment settings. One of the most common causes is when theProcessing Extentenvironment setting is configured in a way thatexcludesthe actual input features.

TheUniontool requires that input features fall within the set extent. If the Processing Extent does not cover any part of one or more input features, they are considered invalid and flagged with a red X, preventing the tool from running.

The software checks whether all input features are accessible within the defined extent. If they are not, this pre-validation error is triggered—even if the inputs are valid in terms of geometry or feature type.

Option A is incorrect because geometrical intersection is not a requirement for Union to run—it simply overlays features and includes all areas.

Option C is also incorrect, as the Union tool does indeed require polygon feature classes, but if incorrect feature types are used, a different error (not a red X related to extent) is shown.

This confirms that the red X in this scenario is caused by the Processing Extent settings not including the input features, making the correct answer B.
