Detailed Solution & Explanation

We are given a group of six persons: A, B, C, D, E, and F. We need to determine the number of female members in this group by systematically analyzing the given relationships. Step 1: Analyze the statement "B is the brother of D but D is not brother of B." From "B is the brother of D", we deduce that B is male. From "D is not brother of B", combined with the fact that B is D's brother (implying D is a sibling of B), it means D cannot be male. Therefore, D must be female. Current Genders: B (Male), D (Female). Step 2: Analyze the statement "F is the brother of B." From this, we deduce that F is male. Current Genders: B (Male), D (Female), F (Male). We now know that F, B, and D are siblings, with F and B being male and D being female. Step 3: Analyze the statement "C and A are married together." This implies that C and A form a married couple. One must be male and the other female. Their specific genders are not yet determined from this statement alone. Step 4: Analyze the statement "F is son of C but C is not the mother of F." We already know F is male (from Step 2). "F is son of C" means C is a parent of F. "C is not the mother of F" means C is not female. Since C is a parent, C must be the father of F. Therefore, C is male. Current Genders: B (Male), D (Female), F (Male), C (Male). Step 5: Combine information from Step 3 and Step 4. From Step 3, C and A are married. From Step 4, C is male. For C and A to be a married couple, if C is male, then A must be female. Current Genders: A (Female), B (Male), C (Male), D (Female), F (Male). We now know that C (Male) and A (Female) are the parents of F, B, and D. Step 6: Analyze the statement "E is the brother of A." From this, we deduce that E is male. Current Genders: A (Female), B (Male), C (Male), D (Female), E (Male), F (Male). Step 7: Summarize the gender of each person in the group. A: Female B: Male C: Male D: Female E: Male F: Male Step 8: Count the number of female members in the group. The female members are A and D. Total number of female members = 2. Therefore, the correct choice is **Option B**.
