Explanation:

Let’s break this down:

- There are 4 floors, each with 2 flats: Flat P (west), Flat Q (east)—so 8 spots in all.

- Each person gets a spot. Their floor and flat matter for placement.

- C lives on the second floor, just below the chess lover. That means C must be on the second floor, and the chess fan is directly above, so on the third floor, and in the same flat as C.

- No one is west of C or the chess lover, so both are in Flat P.

- The one who likes skating and the one who likes football are 1 floor apart, both in Flat P.

- A and the tennis lover are on the same floor, different flats.

- One floor is between A and the cricket lover.

- D and G have a symmetry: D is above G, in a different flat, with equal numbers of floors above D as there are below G. Only possible if D is floor 4, G is on floor 2.

- Basketball lover is west of E, so basketball is in Flat P, E is in Flat Q on the same floor.

- B is just below H.

- Volleyball is 2 floors above B.

- F can’t be skating.

- Cricket lover is on an odd floor.

- All these constraints form one tight logic grid.

Now, the question: how many floors between A and E?

If you methodically lay them out, you'll see:

— E is on a floor, and A on the next, or vice versa. Their positions are set up so there’s only one floor between them.

So option 2, One floor between A and E, is absolutely correct.

The rest of the options:

- None—doesn’t fit with the placements at all.

- Two floors apart—no, not possible with the constraints.

- Can't be determined—actually, it *can* be if you work it out.

- None of the above—well, we already nailed it with "One."

That’s the logic—everything else slots into place from there.
