Detailed Solution & Explanation

Let us reconstruct the expression by mapping the placeholder symbols to their correct operators: - '%' maps to '+' ('is the son of') - '=' maps to '-' ('is the daughter of') - '&' maps to '*' ('is the wife of') So the expression 'A % B = C & D' becomes 'A + B - C * D'. Let us analyze the relationships step-by-step: 1. 'C * D' means C is the wife of D. This implies D is the husband of C (D is male). 2. 'B - C' means B is the daughter of C. 3. Since B is the daughter of C and C is married to D, D must be the father of B. 4. 'A + B' means A is the son of B (this defines the next generation but does not affect the relationship between B and D). Therefore, D is the father of B. Hence, **Option B** is the correct answer.
