Concept:Land is a natural factor of production with several distinct characteristics, one of which is that its quality varies from place to place.
Explanation:Land is fixed in supply, so it cannot be described as having elastic supply.
It is a passive factor of production because it needs labour and capital to be productive, not an active factor.
The most important feature here is that land is heterogeneous in nature.
This means land differs in fertility, location, climate, and mineral content from one area to another.
Returns to scale apply when all inputs are changed together, so this does not describe land alone.
Answer:C. is heterogenous in nature.
