Final answer:
Family systems theory emphasizes the relationships and interactions between family members (Option B).
Step-by-step explanation:
In family systems theory, a family is seen as more than just the sum of its individual members; it is viewed as a complex, interconnected system where the whole is greater than the sum of its parts. Family systems theory emphasizes the relationships and interactions between family members and how these dynamics impact the entire family unit. For example, if there is a change in one family member, such as a parent losing their job, it will likely affect the entire family's financial situation and may lead to changes in other family members' roles and responsibilities.
Thus, the statement that is inaccurate about family systems theory is B) A family as a whole is equal to the sum of the individual members.
