In a dice a, b,c and d are written on the adjacent faces in a clockwise order.
Now, on the opposite side of ‘a’ is ‘c’.
Therefore, when c is on top, a will be on bottom.

Here, a pattern is followed in the first two figures. The figure which is on the inside becomes the figure which encloses the outside figure in figure 2 of the pattern.
Therefore, the correct option obtained on following the pattern is option D as the hexagon should enclose the diamond in answer figure.
The correct option is option D.

Thus, F and I live on 1st floor, B, C and G live on 2nd floor and A, E live on 3rd floor.
D and H live in 1st and 3rd floor in any order.
Thus, the table is:-

We cannot determine who lives in a B house without any further information.
Hence, option E is the correct answer.

A lives on 3rd floor.
E lives on a floor above G whereas G lives on a floor above I.
Thus, E lives on 3rd floor, G lives on 2nd floor and I lives on 1st floor.
C and B live on the same floor
Already 2 people live on 3rd floor. Thus, B and C either live on 2nd or 1st floor.
F live in 1A and already I lives on 1st floor.
Thus, B and C must live on 2nd floor.
Thus, F and I live on 1st floor, B, C and G live on 2nd floor and A, E live on 3rd floor.
D and H live in 1st and 3rd floor in any order.
Thus, the table is:-

Thus, if H and I have the same lettered house then they must live on different floors.
Thus, H lives on 3rd floor.
Thus, D must live on 1st floor and more particularly in 1B.
Hence, option D is the correct answer.

A lives on 3rd floor.
E lives on a floor above G whereas G lives on a floor above I.
Thus, E lives on 3rd floor, G lives on 2nd floor and I lives on 1st floor.
C and B live on the same floor
Already 2 people live on 3rd floor. Thus, B and C either live on 2nd or 1st floor.
F live in 1A and already I lives on 1st floor.
Thus, B and C must live on 2nd floor.
Thus, F and I live on 1st floor, B, C and G live on 2nd floor and A, E live on 3rd floor.
D and H live in 1st and 3rd floor in any order.
Thus, the table is:-

Thus, we can determine the floor on which a person lives for 7 people.
Hence, option B is the correct answer.
