Answer :
Staying married for the children can be detrimental in ongoing high-conflict situations, as children might benefit from the reduction of conflict after a divorce from such marriages. Hence the correct option is 2) detrimental
For couples who have ongoing marital conflict, staying married "for the sake of the children" may be detrimental based on research findings on the effects on children. While some long-term studies suggest that high-conflict marriages may lead to better outcomes for children if the parents decide to divorce, there is evidence that children fare worse when parents end low-conflict marriages. Marital conflict preceding the divorce and the subsequent poverty are significant factors affecting children negatively, but divorce from a highly contentious marriage can be beneficial for both spouses and children, reducing the exposure to harmful conflict.
