Which example best illustrates relocation diffusion of crops with settlers?

• A. Spread of crops like potatoes and maize to new regions with settlers
• B. Spread of social media usage globally
• C. Language revival within a single nation
• D. Preservation of indigenous crafts without external contact

Answer: (A)

Relocation diffusion happens when people move and carry their cultural traits with them to new places, spreading them as they settle. Bringing crops along with settlers illustrates this because seeds, farming knowledge, and agricultural practices travel with the migrating population and take root in the new lands they settle.

So, the spread of crops like potatoes and maize to new regions with settlers is the best example, since the crops move specifically because people are moving and establishing new agricultural systems. The other scenarios involve diffusion through networks or internal change rather than the physical movement of people carrying crops to new areas.
