The introduction of Indian spices in Kenyan cooking and the adoption of sushi from China into Japanese cooking is an example of cultural diffusion.
Answer: Option D
<u>Explanation:</u>
Cultural diffusion simply refers to mixing of cultures. Cultural diffusion takes place when people of one culture adopt some features of people of other cultures. Kenyan people using Indian spices in cooking means that they are using ideas of the Indian culture to make their cuisine taste better.
Similarly, adoption of Sushi into Japanese cooking means that Chinese culture is being spread among the people of Japan. Cultural diffusion allows a culture to have a wide base and makes it popular across the globe.
