In a code, "P + Q" means P is the father of Q, "P − Q" means P is the sister of Q, and "P × Q" means P is the brother of Q. What does "A + B − C" mean?
Correct answer: B. A is the father of C.
"A + B" means A is the father of B, and "B − C" means B is the sister of C. B and C are siblings, so A is the father of C as well.
