Which of the following is an example of relocation diffusion?

Relocation diffusion refers to the spread of ideas, innovations, or cultural practices through the physical movement of people from one place to another. In the context of the given options, moving from one house to another in a new neighborhood exemplifies this concept. When people relocate, they often bring with them their cultural practices, beliefs, and values, which can influence the new community they join.

The other options describe different types of diffusion or cultural transmission. Innovation spreading through digital platforms is an example of expansion diffusion, where ideas spread quickly through technology without the physical relocation of individuals. A fad that sweeps through a community reflects a trend that spreads rapidly, often through social interaction, but does not involve the relocation of people. The influential artist showing their work in various cities also exemplifies the diffusion of cultural influence through exposure, rather than through physical movement of people carrying the culture with them. Thus, option C is the most fitting example of relocation diffusion.
