What application can be used by users to create a survey in ArcGIS Online?

ArcGIS Survey123 is specifically designed for creating surveys within the ArcGIS Online environment. This application allows users to design, share, and analyze surveys that can collect geospatial data effectively. With its intuitive interface, users can build surveys that include various question types, incorporate logic, and collect location information, making it particularly suited for field data collection and public engagement.

The other applications listed serve different purposes within the ArcGIS ecosystem. For instance, ArcGIS Dashboard Builder is focused on creating dashboards to visualize data, ArcGIS Map Viewer is used for mapping and visualizing geographic information, while ArcGIS Story Maps is intended for combining maps with narrative text and multimedia to tell a story. Each of these applications has its unique functions, but they do not offer the specific capabilities for survey creation that ArcGIS Survey123 provides.
