Explanation:

The definition of cultural diffusion is: the spread of the beliefs and social activities of one culture to different ethnicities, religions, nationalities, etc. (yourdictionary.com) The Saudi Arabia answer choice is incorrect because that is simply the exportation/importation of goods. The United Kingdom answer choice is incorrect because that's just two countries becoming allies. The Asia answer choice is incorrect because although both Asia and Africa use paints to create works of art, they are creating their own cultural pieces. What I mean by that is both are using paints but for different works that mean different things.
