Correct Solution: Option D

Step-by-step Solution:

Logical Deduction

The clues "The Doctor is the grandfather of F" and "B is the mother of F and E" immediately establish a three-generation family. B is the mother in the middle generation, and the Doctor is the grandfather in the top generation.

We are given two married couples: (1) Manager D is married to A, and (2) Jeweller C is married to the Advocate.

Since B is the mother, she must be part of a married couple. From the pairs above, she must be the Advocate, which means her husband is C, the Jeweller. This pair makes up the parent generation.

The other married couple, D (Manager) and A, must therefore be the grandparents.

We know the grandfather's profession is Doctor. Since D's profession is Manager, it logically follows that A must be the Doctor and, therefore, the grandfather of F and E.

Final Family Structure


Grandparents: A (Doctor) & D (Manager)
      |
Parents:      C (Jeweller) & B (Advocate)
      |
Children:     F (Psychologist) & E (Engineer)

Conclusion:Profession of A is Doctor

Final Answer: The correct option is D
