Which of the following is NOT one of the categories of land use districts?

The correct response is that "Educational" is not one of the traditional categories of land use districts. In urban planning and land use policies, areas are typically categorized into several main types, with Residential, Commercial, and Agricultural being the most common classifications.

Residential districts are designed primarily for housing and living spaces. Commercial districts are focused on business activities and include retail, office space, and services. Agricultural districts are reserved for farming and related activities. While educational facilities do exist and can have designated zones, they are usually encompassed within broader categories like Residential or Commercial rather than having a distinct land use category on their own.

Thus, the absence of "Educational" from the common land use district classifications corroborates the identification of it as the correct answer.
