Explanation
Risk impact assessment involves calculating the impact of identified risks. Risk analysis is the process of examining, estimating, and evaluating the impact of risks, which helps in calculating the impact (Reference:

Explanation
Project risks should be closed when the stakeholders agree a risk is no longer applicable. This ensures that risks are actively managed and only relevant risks are considered throughout the project lifecycle.
According to the PMI Risk Management Professional (PMI-RMP) Reference Materials, project risks are uncertain events or conditions that may have a positive or negative effect on one or more project objectives1.
Project risks can be closed when they are no longer applicable to the project or its activities. The process of closing project risks involves verifying that the risk responses have been completed, documenting the outcomes, and evaluating the effectiveness of the risk management process2. The decision to close a project risk should be made by the stakeholders who are responsible for or affected by the risk, as they are the ones who can determine whether the risk is still relevant or not. Therefore, the correct answer is B. When the stakeholders agree a risk is no longer applicable.

Explanation
The project manager should consider stakeholders' positions and opinions regarding the project's output when engaging stakeholders. This approach helps to address stakeholders' concerns, expectations, and potential objections, and it can lead to better decision-making and more successful project outcomes. It is important for the project manager to maintain open communication with stakeholders and to be responsive to their needs and perspectives.

The risk manager is responsible for ensuring that all risks, including secondary risks, are identified and addressed during the risk response planning process. If key secondary risks were missed, the risk manager should be held accountable. (Reference: Project Management Institute. A Guide to the Project Management Body of Knowledge (PMBOK Guide) - Sixth Edition, Section 11.5) The risk manager is responsible for identifying and analyzing risks, as well as planning and implementing risk responses. Secondary risks are those risks that arise as a direct result of implementing a risk response to a specific risk. The risk manager should have considered the potential secondary risks during the risk response planning and updated the risk register accordingly. The project manager should hold the risk manager accountable for missing the secondary risks and ensure that they are properly addressed12
