According to research,which of the following is TRUE of stepfamilies,or blended families?

A) Mixed loyalties can cause stress.
B) Girls are more likely than boys to accept a stepfather as a parent.
C) Stepmothers are very attached to stepchildren.
D) Remarried mothers use harsher discipline.

Research suggests that mixed loyalties and conflicting family relationships can cause stress and difficulty in stepfamilies, particularly in the early stages of blending. While some stepmothers may develop strong attachments to their stepchildren, this is not universally true, and there is no evidence to support the idea that remarried mothers use harsher discipline or that girls are more likely to accept stepfathers as parents.
