The statement accurately describes the core functionality of Progressive Profiling within Marketing Cloud Account Engagement forms. This feature is designed to conditionally display new form fields to a returning prospect based on whether data for other, pre-specified fields already exists in their prospect record. This allows for a gradual collection of information over multiple interactions without repeatedly asking for the same data, thereby reducing form friction and enriching the prospect's profile over time.

The "False" option is incorrect because the scenario described—showing fields only if other fields are already populated—is the precise definition and intended use case for Progressive Profiling in Account Engagement.

1. Salesforce Help Documentation, "Progressive Profiling for Forms": This official document states, "Progressive profiling displays new fields to prospects based on the data that has already been collected... You can set a form field to display only when another field on the same form has a value." This directly confirms that fields are shown based on pre-existing data in other selected fields.

2. Salesforce Trailhead, "Pardot Lead Generation for Pardot Lightning App" module, "Create a Form" unit: This official training material explains the feature: "Progressive profiling lets you gather information from prospects over time without overwhelming them with a long form. You can configure fields to appear conditionally, based on other fields that the prospect has already completed."
