Explanation
A trend analysis is a technique that examines project performance over time to determine if performance is improving or deteriorating. A trend analysis of risks can help the project manager and the sponsor to identify the patterns and causes of risks, and to take appropriate actions to mitigate or avoid them. In an agile project, the project manager should use the project risk register tracking tool and the issues log to perform a trend analysis of risks. The project risk register tracking tool is a tool that records the identified risks, their probability, impact, response strategies, and status. The issues log is a document that records the issues that arise during the project, their resolution, and their impact on the project. By extracting the data from these two sources, the project manager can provide the sponsor with a comprehensive and accurate trend analysis of risks. Option B is the best answer because it uses the most relevant and reliable sources of information for the trend analysis of risks. Option A is not a good answer because it does not address the sponsor's request for a trend analysis of risks, and it may waste time and resources by brainstorming on general risks that are not specific to the project. Option C is not a good answer because it does not provide a trend analysis of risks, and it may notinclude the latest information on the risks that the project has monitored. Option D is not a good answer because it does not provide a trend analysis of risks, and it may not be relevant or helpful to the sponsor's decision-making process.
