Which of the following is an example of a nonconforming use?

A nonconforming use refers to a property use that does not comply with current zoning regulations but was legally established before those regulations were put in place. In this case, a commercial shop located in a strictly residential zone exemplifies a nonconforming use because it operates in a manner that is inconsistent with the zoning laws applied to that area. While it may have initially been permitted, its continued operation contradicts the present zoning requirements, which have deemed the area suitable solely for residential purposes.

In contrast, a newly built residential area, a vacant lot waiting for development, and a park established in an industrial area either comply with existing zoning regulations or represent transitional uses that do not qualify as nonconforming. The park may serve a community function within an industrial zone, but would not typically contradict zoning; instead, it reflects a permitted or accepted use within the prevailing regulations.
