Conflict resolution

[suresi00]

During a post-mortem meeting, discussion arises about who has to take
responsibility for some major failures. It has become obvious that the attendees
of the meeting will not come to a jointly accepted conclusion.
What is not an appropriate strategy for such a situation?
o Separate the people from the problem
o Focus on interests, not positions
o Insist on objective criteria and standards
o Suspend the discussion and schedule another meeting

Here is the answer is D, is it because that even if postpone(withdraw) it will come back?

what is the explanation provided?
Withdraw is ok when u have a lot of time and you expect that parties in conflict will turn around after cool off period. Questions does not hint anything of that
Is difficult for me to choose D, as all other options also look correct based on limited information provided in the question.
