Final answer:
The correct answer is option a. Option a, which lists wheat, automobiles, and transistor radios, respectively represents land-, labor-, and capital-intensive commodities. Wheat requires significant land, automobiles require extensive labor, and transistor radios need considerable capital investment in technology and equipment.
Step-by-step explanation:
The question refers to different types of commodities and their intensities in terms of land, labor, and capital. To correctly identify which commodities are land-, labor-, and capital-intensive, we must analyze what these terms mean. Land-intensive commodities require large amounts of land to produce, labor-intensive commodities necessitate much human effort, and capital-intensive commodities demand significant investment in machinery and equipment.
Let's consider the options given:
- Wheat, which is a staple crop, generally requires large expanses of land to grow, making it land-intensive.
- Automobiles require a great deal of human effort in assembly and production processes, making them labor-intensive.
- Transistor radios, like many electronics, require a high level of technology and machinery to produce, which makes them capital-intensive.
Taking this information into account, the option that represents land-, labor-, and capital-intensive commodities respectively is a. Wheat, automobiles, and transistor radios.
