Which markup language is designed to store and transport data in a structured, self-describing format?

• A. Trigger
• B. Xml
• C. Unit Testing
• D. While Loop

Answer: (B)

XML is designed to store and transport data in a structured, self-describing format. It uses tags to label data and define its structure, so both humans and machines can understand what the data means and how it relates to other data. This self-describing nature, plus the hierarchical, extensible structure, makes XML ideal for exchanging information between different systems and platforms. For example, a small snippet shows data wrapped in meaningful tags like a customer with a name and email, which conveys both the values and their relationships. The other options aren’t markup languages for data interchange. A trigger is a database-side program that runs in response to events, unit testing is a method for validating code, and a while loop is a control flow construct for repeating actions.
