Explanation:
According to the scenario, you can use the following inputs in order to generate performance reports:
WPI: Work performance information is the data gathered on the status of the project schedule activities that are performed to accomplish the project work. This data is collected as part of the Direct and Manage Project Execution processes. WPI includes the following:
Deliverables status

Schedule Progress

Costs incurred

WPM: Work performance measurements are created from the work performance information. WPMs are an output of Control schedule, Control cost, and Control scope processes, which are monitoring and controlling processes. WPMs consist of planned versus actual performance indicators with respect to scope, schedule, and cost. They are documented and communicated to the stakeholders and are used to make project activity metrics, such as the following:
Planned vs. Actual Technical performance and Scope performance

Planned vs. Actual Schedule performance

Planned vs. Actual Cost performance

Incorrect Answers:
A: Variance analysis is an after-look at what caused a difference between the baseline and the actual performance. It is one of the tools and techniques used for report performance.
D: Change requests are requests to expand or reduce the project scope, modify policies, processes, plans, or procedures, modify costs or budgets or revise schedules. These requests for a change can be direct or indirect, externally or internally initiated, and legally or contractually imposed or optional. A Project Manager needs to ensure that only formally documented requested changes are processed and only approved change requests are implemented.
