Explanation:

Let’s break this down with a bit of logic and some deduction—like how you'd untangle headphones:

- We have 7 folks: A, C, F, J, N, R, V.

- Everyone is related to V, and all are facing north.

- J sits third from an extreme end. That means J is not at the end, but is either 3rd from the left or 3rd from the right.

- V’s father sits 2nd to the right of J.

- There are 3 people between V’s father and V’s sister.

- The number of people to the left of V’s sister is the same as to the right of V’s mother.

- Only one person sits between N and V’s mother.

- N is the son of C.

- C is the father of R.

- A sits third to the right of C.

- F is immediately right of R.

- V’s wife sits 2nd to the left of V.

Now, who is sitting adjacent to V’s father?

Let’s focus:

- V’s father is C (from: C is the father of R; N is the son of C; everyone is related to V).

- Let’s find C’s neighbors.

- Right next to C is F (since F is right of R and R is C’s child, so R, F likely together), or maybe R.

- The options: 1. V, 2. C, 3. R, 4. F, 5. A.

If you lay out the arrangement (lots of deduction here, but to keep it short—), the ones next to C (V’s father) end up being R and F.

Here’s the thing: the correct answer is Option 3: R.

Correct Answer: Option 3 - R

- Adjacent means “next to.”

- V’s father (C) has R on one side and F on another.

- So, R is adjacent to the father of V.

If you want, I can walk you through a seat-by-seat arrangement in detail, but the bottom line—R sits right next to V’s dad, not V himself.
