There are seven risk responses for any project. Which one of the following is a valid risk response for a negative risk event?

Enhance is a positive risk response strategy used to increase the probability or impact of an opportunity, not a response to negative risks.

Exploit is a positive risk response used to ensure an opportunity definitely occurs, and it has no application to negative risk events.

Acceptance acknowledges that a negative risk exists and decides to take no preemptive action, either because the cost of other responses exceeds the risk's impact (passive acceptance) or by preparing a contingency plan to execute if the risk occurs (active acceptance). It is explicitly classified in the PMBOK framework as a valid response for both negative risks and positive opportunities.

Share is a positive risk response that allocates ownership of an opportunity to a third party better positioned to realize it, not a strategy for negative risks.
