Explanation: The risk register is updated at the end of the plan risk response process with the information that was discovered during the process. The response plans are recorded in the risk register. Project management plan consisting of WBS, schedule baseline and cost performance baseline should be updated. After planning risk response process, there may be requirement of updating project documents like technical documentation and assumptions, documented in the project scope statement. If risk response strategies include responses such as transference or sharing, it may be necessary to purchase services or items from third parties. Contracts for those services can be prepared and discussed with the appropriate parties.
Incorrect Answers:
B: Controls are implemented in the latter stage of risk response process. It is not immediate task after the planning of risk response process, as updating of several documents is done first.
The purpose of the Plan Risk Responses process is to develop risk responses for those risks with the highest threat to or best opportunity for the project objectives. The Plan Risk Responses process has four outputs:

• Risk register updates
• Risk-related contract decisions
• Project management plan updates
• Project document updates
