Final answer:
KFC adapted to local tastes in Japan by switching to offering rice bowls, reflecting customer preferences and aligning with traditional Japanese cuisine.
Step-by-step explanation:
The food item that KFC switched to in Japan due to customer preferences is B. Rice. In adapting to local tastes, KFC in Japan began offering rice bowls, which are more in line with traditional Japanese cuisine and are broadly preferred by customers there. This change showcases KFC's willingness to cater to regional tastes and dietary habits, maintaining the brand's global presence while respecting local culinary customs.
