To answer this question, the user needs to have knowledge about the different options available in the Analysis tool of load testing software.
Option A: Drill Down is a feature that allows the user to view more detailed information about a specific data point in a graph. It does not provide an option to see the results of two graphs from the same load test scenario in a single graph.
Option B: Apply Filter allows the user to filter the graph data, for example, by selecting a specific time range, HTTP response code, or transaction name. It does not provide an option to see the results of two graphs from the same load test scenario in a single graph.
Option C: Merge Graphs is the correct answer. This option allows the user to combine two or more graphs from the same load test scenario into a single graph. This is useful when you need to compare the results of different load tests or different types of data.
Option D: Auto Correlate is a feature that automatically detects and correlates dynamic values in a load test script. It does not provide an option to see the results of two graphs from the same load test scenario in a single graph.
Therefore, the answer is:
The Answer is: C. Merge Graphs
