A pre-mortem is a session where all stakeholders meet to come up with a list of potential points of failure and figure out how to mitigate them. Since the team will offer failure avoidance resolutions, the business owners’ participation
is a must because they’ll need to agree with the team’s ideas. The other responses are incorrect. Since business requirements are identified before a pre-mortem, they are the source of the discussion; by the time a pre-mortem occurs,
all team members have been identified; at the point of conducting a pre-mortem, it’s unlikely the team would envision everything working as planned.
