Explanation:

Let’s break down the clues first:

- 8 people: A, B, C, D, E, F, G, H

- Building has 4 floors, each floor has Flat 1 (west) and Flat 2 (east).

- *B lives above C, in different flats, and 2 floors between them (e.g., C on 1, B on 4).*

- *F lives immediately above C.*

- *A lives west of D (so same floor, A in Flat 1, D in Flat 2), and on an odd floor.*

- *No one is west of G, who lives on 4th floor (so G must be in Flat 1, 4th floor).*

- *H does not live on 1st floor.*

Let’s work through it:

- G must be in Flat 1 (west), 4th floor.

- Suppose B is in Flat 2, 4th floor; then C must be in Flat 1 or 2, 1st floor.

- C and F: F lives immediately above C. So if C is on 1st, F is on 2nd (but 4th and 1st are the most separated for B and C).

- If C is in Flat 1, 1st floor, B will be 4th floor, but in Flat 2.

- F would be in Flat 1, 2nd floor.

- A and D: A is west of D (means same floor, Flat 1 and Flat 2, on odd floor, so floor 1 or 3).

- H not on 1st floor.

Let’s locate F:

- C: Floor 1, Flat 1

- F: Floor 2, Flat 1

Who is in Flat 2, 2nd floor? That’s just east of F.

Let’s review options for “who lives just east of F”: (Flat 2, 2nd floor)

- Is it A? A must be in Flat 1, odd floor, west of D. So could be 1st or 3rd floor only.

- Is it C? C is in Flat 1, 1st floor.

- Is it D? D must be east of A, on odd floor, so could be 1st or 3rd floor, Flat 2.

- Is it H? It could be. Let's check if there are contradictions.

- Is it B? B is in 4th floor, Flat 2.

So, on the 2nd floor:

Flat 1: F

Flat 2: H (no contradiction, since H can't be on 1st floor, and fits into 2nd).

So, the person just east of F is H.

Option 4: H

---

Explanation in bullets:

- G is on top west (Floor 4, Flat 1).

- B is on Floor 4, but Flat 2, two floors above C.

- C is on Floor 1, Flat 1; F is above C (Floor 2, Flat 1).

- A is on Flat 1, odd floor; D is east of A (meaning Flat 2, same odd floor).

- H does not live on the 1st floor. 2nd floor, Flat 2 allows this.

- So, just east of F (2,1) is H (2,2).

- Correct answer: Option 4: H
