Step 1: Understanding the Concept:
The question asks for an example of a traded product whose production is primarily determined by climate. The passage mentions "climate" as one of the physical factors leading to uneven distribution of natural resources.
Step 3: Detailed Explanation:
\[\begin{array}{rl} \bullet & \text{(A) Textiles: Production depends on labor costs, industrial infrastructure, and raw materials (like cotton, which is climatic, but textiles themselves are manufactured).} \\ \bullet & \text{(B) Porcelain: Production depends on specific raw materials (kaolin clay) and skilled craftsmanship, which are geological and cultural factors, not climatic.} \\ \bullet & \text{(C) Banana: Bananas are a tropical fruit. Their cultivation is heavily dependent on the specific climatic conditions (temperature, rainfall) found in tropical regions. Countries in non-tropical climates must import them. This is a direct result of climatic factors.} \\ \bullet & \text{(D) Batik cloth: This is a handicraft whose production is based on cultural tradition and skill, not climate.} \\ \end{array}\]
Step 4: Final Answer:
The export of bananas from tropical regions is the best example of trade driven by climatic factors.
