Why this is correct:
XSL (Extensible Stylesheet Language), and specifically XSLT (XSL Transformations), is used to transform XML and to specify presentation rules. XSL is the standard family for styling/transforming XML. Why the others are wrong: 1.      DTD defines XML document structure (markup), not style sheets. 2.      XTL is not the standard name for XML styling (not widely used/standard). 3.    CSS is primarily for HTML/CSS; while CSS can be applied to XML in limited ways, the standard stylesheet language for XML is XSL/XSLT.
