Explanation:

Let’s break this down step by step:

- The row has 8 seats, and everyone faces north.

- “Three persons are sitting between A and H. Either A or H sits second from the right end.”

- So, A and H must be separated by three seats, and one of them is second from the right.

- The row looks like: _ _ _ _ _ _ _ _

- Let’s suppose H is second from right (seat 7), then A must be seat 3. (Count: 3 spots between).

- “One person sits between H and B.”

- With H at 7, B could be 5 or 9, but seat 9 doesn’t exist. So, B is at seat 5 (left of H)

- “B is not sitting to the right of H.”

- Perfect, B is to the left.

- “Three persons are sitting between B and C.”

- B is 5. So, C can be at 1 or 9. Only seat 1 exists.

- “E is not an immediate neighbor of A and B.”

- So E can’t go next to A (seat 3) or B (seat 5).

- “F sits fourth to the left of E.”

- So E must be at least 5th or higher seat (as there must be space on the left), so possible E: 6, 7, or 8.

- If E is 6, F is 2. If E is 7, F is 3—But 3 is already A. So E is 6, F is 2.

- “G is not an immediate neighbor of B.”

- So G can’t be seat 4 or seat 6.

So now, filling up:

1. C

2. F

3. A

4. (Can’t be G)

5. B

6. E

7. H

8. (Can’t be G, E)

We still have D and G to place.

- G can’t be 4 or 6. G can only be 8.

- D gets seat 4.

So the final seating is:

1. C

2. F

3. A

4. D

5. B

6. E

7. H

8. G

Now, count seats between G (8) and H (7):

? There are Zero persons between them.

Let’s check all options:

1. One

2. Two

3. Three

4. Four

5. Five

So, the right answer is Option: None of these (but if you consider the closest, which is zero—not an option).

What this really means is: Between G and H, there’s nobody sitting. They are right next to each other. So none of the provided options matches reality. If you had to pick from 1–5, the closest is 1—since they’re immediate neighbors, but really, the answer is zero.

Hope that clears it up!
