Which statement best describes the relationship between REST and browser clients regarding data formats?

• A. REST uses XML to communicate with browsers
• B. JSON predominates, improving support for browser clients
• C. REST is not compatible with browsers
• D. REST requires XML for browser use

Answer: (B)

Data formats in REST and how browsers consume them is about choosing something easy for web apps to handle. JSON has become the dominant format for REST responses because it’s lightweight, directly maps to JavaScript objects, and is quick for browsers to parse with built-in tools. This makes REST data simple to consume in browser-based clients, enabling dynamic pages and apps to work smoothly without extra parsing steps. REST can return other formats like XML, but JSON’s ubiquity in web development and its strong compatibility with browser environments is why this statement is the best description. XML tends to be more verbose and less convenient for typical browser-driven workflows, and REST is not restricted to XML or incompatible with browsers, so those options aren’t as accurate.
