Correct Answer

✅ Option c — D is the uncle of F

All Options:

  • AD is the father of F
  • BD is the grandfather of F
  • CD is the uncle of F
  • DD is the brother-in-law of F

Detailed Solution & Explanation

We are given the following relations: - A+B  ⟹  \displaystyle A + B \implies A is the father of B - A×B  ⟹  \displaystyle A \times B \implies A is the brother of B
Let us decode the given expression **D×E+F\displaystyle D \times E + F** step-by-step: 1. **D×E\displaystyle D \times E**: This means D is the brother of E. 2. **E+F\displaystyle E + F**: This means E is the father of F.
Combining these two relations: - E is the father of F. - D is the brother of E (F's father). - Therefore, D is the uncle of F. Hence, **Option C** is the correct answer.
