For automating the advancement of university admission application cases based on standardized test scores, the correct configurations would be:

A. Configure a process with a decision shape that continues if the TestThreshold configuration setting is less than the applicant’s test score. This configuration directly supports the requirement by placing a decision shape in the process that compares the applicant's test score against a pre-configured threshold. If the score exceeds the threshold, the case advances, automating the workflow based on performance.

D. Configure a TestThreshold Configuration setting with the national average for the test score threshold. This option involves setting a dynamic threshold that adjusts based on the national average each year. It ensures that the decision shape in Option A has a relevant and up-to-date threshold to compare against.

Options B and C are incorrect because B involves calculating the average rather than setting a threshold, and C incorrectly states the comparison logic.
