Which of the following formats is NOT a standard data-exchange format commonly used for OmniScript output?

• A. JSON
• B. XML
• C. HTML
• D. REST

Answer: (C)

When exchanging data between systems, the formats you rely on are machine-readable and easy to parse. JSON and XML are the classic data-interchange formats because they encode structured data in a way that other systems can consume reliably. REST, while not a data format itself, describes how to access resources over HTTP and typically uses JSON or XML for its payloads, so it fits the idea of data interchange patterns rather than a presentation format.

HTML, by contrast, is designed to render content for humans in a browser. It encodes how data should be displayed rather than providing a structured data payload that another system can easily parse. Because of that, HTML is not considered a standard data-exchange format for OmniScript output, which is why it’s the correct choice.
