Structured data refers to a standardized format for providing information about a page and classifying the page content. It is often implemented through markup languages such as JSON-LD, Microdata, or RDFa, allowing search engines to better understand the context of the content on a webpage. By using structured data, website owners can enhance their search engine visibility, facilitate rich snippets in search results, and improve user experience.

Saying that structured data is a markup language is accurate because it relies on these markup formats to describe and organize content. This form of markup enables search engines to interpret and retrieve relevant data more effectively, thereby improving how information is displayed in SERPs (Search Engine Results Pages).

The options that refer to structured data being limited to certain contexts or formats, such as only for web pages or only for images, do not capture the broader applicability and flexibility of structured data across various types of content on the web. Thus, the statement that structured data is a markup language is a fundamental truth in SEO practices.
