Step 1: Understanding the Concept:
Using the family tree from the previous question, we identify the middle-generation couple and then locate the generation above them.
Step 2: Detailed Explanation:
The couple in the family is A and F. The information states that A is the son of C.
Step 3: Calculation:
Since the family has six members (A, B, C, D, E, F) and we have identified five, B must be the spouse of C. Therefore, B and C are the parents of the couple (specifically A).
Step 4: Final Answer:
The parents of the couple are BC. Thus, the correct option is (b).
