Exam Certified Platform Developer II topic 1 question 126 discussion

A Dynamic Record Choice is a query on an Object in Salesforce that you may add filters to, and have those results presented to your End User for selection. The records that you return will be dynamic based on your filters, and the End User can select one or multiple records to perform an action on.

Process builder and if updated flow can get this accomplished easily. Nothing is mentioned of it being complicated that would require Visualforce and apex.

C is Correct. Visualforce allows you to create custom user interfaces using HTML, CSS, and Apex, and provides the flexibility to create dynamic surveys with conditional questions based on user responses. With Apex, you can define the logic to determine which questions should be displayed based on previous responses, as well as store and retrieve the survey responses. While the other options listed may have some capabilities to address this requirement, Visualforce and Apex are the most suitable options for creating a dynamic survey with custom logic and navigation based on user responses.

I don't see A being a good answer. Ideally you would want to use flow, and although A is a piece of flow, it itself is not a complete solution. Of the options available, D would be best as it implements lightning components, which may have incorporated flow into it. However, it doesn't need to, it can stand alone and is better with being reactive and is better for mobile apps as well.
