Explanation:

Let’s break this puzzle down:

- “Equal number of boxes above and below A” ? A must be in the middle (5th position in a stack of 9).

- “Three boxes between A and B” ? So B is either 1st (above) or 9th (below).

- “Number of boxes above B = Number of boxes below C” ? This hints that B and C are symmetrical around the stack.

- “Two boxes between C and I” ? Positions of C and I are linked, fixed distance.

- “One box between A and G, G NOT immediate above I” ? So, G is either 6th or 4th.

- “No box between F and D, D not above F” ? So D is immediately below F.

- “E below H, which is immediately below D” ? So: F (top), D (right below F), H (right below D), E (right below H).

Putting it all together, here’s how the boxes stack up:

1. F

2. D

3. H

4. E

5. A

6. G

7. C

8. I

9. B

Now, let’s check F and A:

- F is at 1st, A is at 5th.

- Boxes in between: D (2), H (3), E (4).

- That’s three boxes between F and A.

Option 4: Three — 

What this really means is: There are three boxes between F and A, not two. Option 4 is correct.

Option 2 isn’t right, but it was a strong guess—the chain just needed that last link.
