Answer:

B. Mother's mother

Given:

• (A + B) → A is mother of B

• (A - B) → A is brother of B

• (A \times B) → A is wife of B

• (A \div B) → A is father of B

Expression:
F + G × H ÷ I − J

Step-by-step:

1. F + G → F is mother of G

2. G × H → G is wife of H

3. H ÷ I → H is father of I

4. I − J → I is brother of J

---

Build the relation:

• F → mother of G

• G → wife of H ⇒ H is male

• H → father of I

• I → brother of J ⇒ I and J are siblings

So:

• H is father of J

• G is mother of J

• F is mother of G

---

Final relation:

F is mother of G, who is mother of J

---

F is the grandmother of J
