The Lookup element is used to retrieve data from a single field in a Salesforce record. The Lookup element allows the developer to specify the object, field, and filter criteria for the data retrieval. The Select element is used to display a list of options for the user to choose from.

he Aggregation Step in a calculation procedure allows the developer to perform aggregate functions such as SUM, COUNT, MIN, MAX, and AVG on the output of a previous step. The developer can use this step to calculate the sum of the entire base price by specifying the field name and the aggregation function

The PREVIEW tab in OmniScript allows the developer to test the DataRaptor Extract by providing a record ID and viewing the output data. This is a quick and easy way to troubleshoot whether the DataRaptor Extract is retrieving data correctly.

The best answer is D because the requirement combines two constraints: the OmniScript must be embedded on a third-party website and it must be prefilled using URL-passed data. An Experience Cloud page can host the OmniScript, and the third-party website can embed that page in an iFrame while passing URL parameters. Salesforce documentation confirms that OmniScript URL parameters can prefill fields and must use the c__ prefix in URL query-string format. Option A describes the parameter style, but by itself it does not explain how the OmniScript is embedded on the third-party website. Option C is the standard off-platform LWC/OmniOut-style idea, but the question specifically emphasizes URL-based prefill, which fits the Experience Cloud/iFrame pattern more directly.
