Explanation:

Let’s break this down step by step:

- We have 8 people, 3 cities (Delhi, Pune, Hyderabad), and pairs of married couples from two generations.

- No couple works in the same city. At least two people per city, gender balance in each city.

- Designations (seniority): GM > AGM > CEO > Manager > Assistant Manager > PO > Clerk > Sub staff.

- Only three people are senior to B’s son, so B’s son is 4th in rank.

- E is G’s sister-in-law, and G is the most junior (Sub staff). E is married to G’s sibling.

- H is D’s son-in-law; D is next senior to A.

- F is married to C. Neither works in Delhi.

- Hyderabad: Only C and H.

- Delhi: Only PO and Sub staff.

- F is between C and H in rank.

- G is B’s daughter-in-law. B is married to D.

Now, for the question: Designation of the father of G?

- Since G is daughter-in-law, her father-in-law can only be B or D.

- B is married to D, so B could be the father-in-law.

- Let’s look at the structure:

- B is married to D. G is their son’s wife.

- So, B is G’s father-in-law.

Let’s find B’s position:

- G (Sub staff, Delhi)

- Delhi has Sub staff and PO.

- G is married to H or F (let’s say H).

- Only PO and Sub staff in Delhi. G and one other—must be married to someone not in Delhi.

- If G is with H, and H is D’s son-in-law, then D is G’s spouse’s parent.

But, with all clues, the father of G is B.

- Three above B’s son means B’s son is AGM (since GM, AGM, CEO, Manager…).

- So, B (the father) must be AGM.

The correct answer is Option 2: AGM.

Quick Recap (statements explained):

- Equal genders, at least two per city: avoids odd placement.

- Ranking clue tells us B’s son is AGM.

- Married couples in different cities: so, G’s spouse not in Delhi.

- C, H in Hyderabad; so, everyone else in other cities.

- B is G’s father-in-law: by process of elimination, B = AGM.

AGM is the answer.
