What is a key feature of markup languages?

• A. They allow for the execution of logic
• B. They use tags to format and define elements
• C. They are used for data analysis in databases
• D. They enhance the performance of compiled code

Answer: (B)

Markup languages are primarily designed to annotate text or data with specific tags that describe its structure and presentation. This feature of using tags is what differentiates markup languages from other programming languages. Tags help to define elements such as headings, paragraphs, links, and images, thus allowing for a clear organization of content. For example, in HTML, tags like `<h1>` for headings and `<p>` for paragraphs structure content visually on the web while also conveying semantic meaning. This tagging system enables browsers and other software to interpret the materials correctly, rendering them in a manner that is user-friendly. The other options don't align with the core purpose of markup languages. Logic execution is more typical of programming languages, while data analysis is associated with query languages or databases, and performance enhancement relates to compiled languages rather than markup.
