Which of the following is an example of relocation diffusion?

• A. The spread of a new crop variety through human migration.
• B. The adoption of a smartphone within a city through advertising.
• C. The diffusion of a language via media broadcasts within a country.
• D. The spread of fashion trends on social media within one region.

Answer: (A)

Relocation diffusion occurs when people move and bring their practices or traits with them to new locations. Spreading a new crop variety through human migration fits this because migrants carry seeds, farming methods, and knowledge to the places they settle, introducing the crop to new areas as they relocate.

The other scenarios involve ideas or trends spreading without people moving. Advertising to a city spreads the smartphone through local adoption, which is expansion diffusion. Language spreading via media broadcasts within a country also spreads through communication channels rather than through migrants. Fashion trends spreading on social media within a region similarly diffuse through networks without physical relocation.
