b. The lack of or removal of models showing what the marriage role is like.

Explanation:

Although divorce has become more common in recent times, the effect that this has on children is not always well-understood. However, one effect that divorce appears to have on children is the fact that they lose role models for marriage. This means that children of divorced parents do not have a role model that can outline for them what a marriage is supposed to look like. This can lead the child to be unprepared to face his own marriage successfully.
