Explanation:

- There are eight people living in a building with four floors and two flats on each floor.

- B and C live with two floors between them. B is above C and they live in different flats.

- F is placed immediately above C.

- A lives to the west of D and is on an odd-numbered floor.

- No one lives to the west of G, who resides on the fourth floor.

- H cannot be on the first floor.

Analyzing the above:

- G must live in Flat 1 on the fourth floor.

- B must be on the third floor, directly above F.

- F must be on the second floor, directly above C.

- Hence, G (Fl 1/Fl 4), B (Fl 1/Fl 3), F (Fl 1/Fl 2), C (Fl 2/Fl 1).

- A must be in Flat 1 on the third or first floor (odd-numbered).

- D is east of A; therefore, A is on the first floor, Flat 1.

- Thus, placing D in Flat 2, Floor 1.

- H must then be on the third floor in Flat 2.

By this arrangement:

- No person lives to the west of G, confirming G's position.

- H lives just east of F. Therefore, the answer is Option 4: H.
