单项选择题

It should go without saying that the focus of UML is modeling. However, what that means, exactly, can be an open-ended question. (71)is a means to capture ideas,relationships, decisions, and requirements in a well-defined notation that can be applied to many different domains. Modeling not only means different things to different people, but also it can use different pieces of UML depending on what you are trying to convey. In general, a UML model is made up of one or more(72). A diagram graphically represents things, and the relationships between these things. These (73) can be representations of real-world objects, pure software constructs, or a description of the behavior of some other objects. It is common for an individual thing to show up on multiple diagrams; each diagram represents a particular interest, or view, of the thing being modeled. UML 2.0 divides diagrams into two categories: structural diagrams and behavioral diagrams. (74)are used to capture the physical organization of the things in your system, i.e., how one object relates to another. (75)focus on the behavior of elements in a system. For example, you can use behavioral diagrams to capture requirements, operations, and internal state changes for elements.

（75）处填（）。

A．Activity diagrams

B．Use-case diagrams

C．Structural diagrams

D．Behavioral diagrams

某县人民政府为了发展地方经济，吸引外商投资，发布了《关于外商投资土地优惠政策的规定》。该规定指出：凡来本县投资者，投资额超过100万的，县政府免费为投资者提供建设用地。该县一企业家王某认为，该规定对外来投资者和本地商家区别对待，规定的内容与法律的相关内容相抵触，因而请求人民法院依据宪法和法律撤销这一规定。人民法院则认为，该规定属于县政府的行政规定，法院不能受理此案，并告知王某向市政府和市人大反映情况。王某认为法院应当受理此案。
请根据宪法和法律的有关规定进行分析，人民法院的做法是否正确 为什么
