In the context of configuring a Pega Web Mashup gadget, what is the correct syntax to use an element value from the host page?

The correct syntax for using an element value from the host page in a Pega Web Mashup gadget is represented by the choice that uses the format for data attributes specific to Pega. In this case, using data-pega-parameters="{Customer:'[page/id/Account]'}" clearly indicates how to reference a specific value from the host page to be passed into the Pega application.

This syntax leverages Pega's use of data attributes prefixed with data-pega-, specifically the data-pega-parameters attribute, which is designed for passing parameters from the host page to the Pega application. The structure within the curly braces effectively maps to a Pega data page or property, allowing seamless integration of external values that can influence the behavior or presentation of the Pega application.

In contrast, the other choices may not align perfectly with Pega’s expected configurations for mashup parameters. For instance, some might involve incorrect prefixes or syntaxes, or focus on different elements, such as attributes or mappings, that do not directly fulfill the requirement of passing host page data. Therefore, the correct choice not only fits the intended use case but is also formatted in a way that aligns with Pega's best practices for web
