To answer this question, you need to understand the concepts of XML (eXtensible Markup Language) and XSLT (eXtensible Stylesheet Language Transformations).
XML is a markup language that is designed to store and transport data. It is platform-independent and can be used with any programming language. XSLT, on the other hand, is a language used for transforming XML documents into other formats, such as HTML or PDF.
Based on the given question, the correct answer is C) ALL. XML and XSLT are supported by all modern web browsers. This means that you can use XML and XSLT in any browser, such as Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, etc. Browsers provide support for XML and XSLT by implementing the necessary parsers and processors to handle these technologies.
It is worth noting that there might be some differences in the level of support for XML and XSLT between different browsers, but in general, all modern browsers can handle and render XML and XSLT documents.
