Differentiate plantation agriculture from commercial mixed crop and livestock farming.

• A. Plantations are small, diversified family farms near cities; mixed farming is export-oriented.
• B. Plantations are medium-scale farms that produce multiple crops for local markets.
• C. Plantations are urban agriculture projects with limited land.
• D. Plantations are large-scale, single-crop export-oriented operations in tropical regions; mixed crop and livestock farming is diversified and often closer to domestic markets.

Answer: (D)

The main idea here is how scale, crop focus, and market orientation differentiate plantation agriculture from commercial mixed crop and livestock farming. Plantations are large-scale operations that grow a single cash crop for export, usually located in tropical regions and often owned by large companies or foreign interests. The emphasis is on producing one commodity for distant, international markets, with production tied to global supply chains. In contrast, commercial mixed crop and livestock farming blends several crops with livestock, making the farm more diversified and typically oriented toward local or regional markets rather than exporting a single product. This system spreads risk across outputs and tends to be closer to the places where people live and consume, reducing transport costs. So the statement that plantations are large-scale, single-crop export-oriented operations in tropical regions, while mixed crop and livestock farming is diversified and often closer to domestic markets, best captures the key differences. Other descriptions misstate scale, crop variety, or market focus, which is why they don’t fit as well.
