Final answer:
Similar parenting styles are not a sign of a high risk for stress on a family related to the anticipation of a new family member, while lack of social support, difficulty coping with stress, and poverty are potential stress factors.
Step-by-step explanation:
The option that is NOT a sign of a high risk for stress on a family related to the anticipation of a new family member is D) Similar parenting styles. The elements that typically contribute to family stress include A) Lack of social support, B) Difficulty coping with unanticipated stress, and C) Poverty. Each of these can increase stress levels and potentially lead to negative outcomes such as family conflict or child abuse.

Instead, it might actually lead to a more harmonious family environment as there would likely be less conflict over child-rearing approaches.
