If the choices are the following,
a. The sophisticated city look that reflects his business life.
b. Barefoot and serene tropical decor to reflect the lifestyle he wishes he had.
c. Plain, non-stylized environment, neither city nor tropical, so that he won't be reminded of his conflicts.
d. Redefined traditional look with one or two large tropical accessories.
then, choice (b) is correct. Since he wishes to live on a tropical island, it would be best if the decorating plans fit his wishes. By that, he relieves himself from the stress of city life.
