Final answer:
The commercial property in the city spanning one block possesses the characteristic of durability.
Step-by-step explanation:
The type of land that possesses the characteristic of durability is the commercial property in the city spanning one block. This type of land is valuable and has a high demand for various business activities, making it durable in terms of its long-term economic viability.
In contrast, a three-acre farm with four brick-based structures is more susceptible to changes in agricultural practices and economic conditions. The retirement home on one acre of land in the suburbs may also be subject to changes in demographics and market demands.
In conclusion, the commercial property in the city is the most durable type of land due to its potential for continued use and value in urban settings.
