Final answer:
The correct answer is b. store.
Step-by-step explanation:
In the context of the question, the correct answer is b. store. While a single-family house, duplexes, and apartments are all examples of residential use of private land, a store is not. A store is a commercial use of private land where goods or services are sold to customers. Residential use, on the other hand, refers to the use of private land for living purposes such as houses, apartments, or duplexes.
