Explanation:
XML is a markup language, which is not a replacement of HTML and designed to store and display
data. XML stands for Extensible Markup Language. It is a metamarkup language for developing text
documents. This language allows developers and writers to invent the elements they need, as they
need them. This language defines a generic syntax used to mark up data with simple, human readable tags.
Answer A is incorrect. XML is not a programming language. There is no such thing as
an XML compiler that reads XML files and produces executable code.
Answer C is incorrect. XML is a descendant of SGML, which defines a generic syntax used to mark up
data with simple, human-readable tags.
Answer B is incorrect. XML is a markup, cross platform and long-term data format language. The
XML text can be read with any tool that can read a text file.
