Which menu option must be clicked to enable the diagram check feature?

The correct choice of clicking on the "File" menu option to enable the diagram check feature is grounded in the typical user interface design of many software applications, including Cvent. The "File" menu often serves as a primary access point for document settings, options, and configurations. When working within diagramming tools, functionalities like enabling or disabling features are often included under this menu, given that they relate to the overall management and integrity of the document.

Additionally, the consistency in software interfaces means that many critical features, including those for checking the integrity of diagrams, will frequently reside in the "File" menu. This reflects standard practices in applications where settings that affect how the software operates are housed in the "File" area, allowing users to manage features effectively while working on their diagrams.

In contrast, the other menu options typically serve different purposes: "Edit" focuses on modifying existing elements, "View" controls how the diagram is displayed, and "Help" provides assistance or guidance on using the software but does not usually contain critical features like diagram checks. This design helps streamline user experience by organizing functionalities logically.
