To answer this question correctly, it is important to understand how work performance data is transformed into work performance information. Work performance data is produced as a result of project execution. The work performance data can then be analyzed during various controlling processes to produce work performance information (see the image below). Work performance information is only produced as an output during the Monitoring and Controlling Process Group. In this scenario, the question suggests that a variance analysis has been performed using work performance data in order to produce work performance information. Thus, it can be concluded that the process underway is part of the Monitoring and Controlling Process Group, and the two answer choices representing executing processes can be eliminated.

Both the Validate Scope and Control Scope processes produce work performance information as an output. However, only the Control Scope process uses variance analysis to produce work performance information regarding variances in the project work compared to the scope baseline. Therefore, of the available choices, the project manager must be executing the Control Scope process.
