The HTML element contains metadata, title, scripts, styles, and other information that the browser needs but does NOT render directly on the visible page. The contains the visible content.

The tag renders text at a larger font size, specifically one level larger than the surrounding text. While deprecated in HTML5, this was the standard HTML4 tag for increasing font size incrementally. The

tag creates a heading (semantic structure), decreases size, and sets an absolute small size.

In HTML's tag, the 'face' attribute specifies the font family/typeface to use (e.g., face="Arial"). The correct syntax is . The other options are not valid HTML attributes for font selection - 'Character' and 'Text-type' don't exist, and 'Font-type' is not the correct attribute name.

The 'src' attribute in tags specifies the URL of the document to load initially in that frame. This is the default page displayed when the frameset opens. 'def' is not a valid HTML attribute, 'a href' is for anchor links, and the frame must load some document.

HTML is a markup language for describing document structure and content, NOT a protocol. HTTP is the protocol for transferring web content. HTML itself has no protocol functionality.

iBATIS configuration XML requires nested tags: root, containing , , , for settings, and with nested tags. Option C includes all required elements in proper hierarchy.

To answer this question, the user needs to know what XML stands for.

The correct answer is:

C. eXtensible Markup Language

Option A is incorrect because "eXtra Modern Link" is not the correct expansion of XML.

Option B is incorrect because "X-Markup Language" is not the correct expansion of XML.

Option D is incorrect because "Example Markup Language" is not the correct expansion of XML.

Therefore, the correct answer is option C, "eXtensible Markup Language".

A Document Type Definition (DTD) defines the legal building blocks of an XML document, describing its structure and the data elements it contains.

XML declarations must use the processing instruction syntax with . The version attribute is required, and the declaration must not have a trailing slash like regular tags. Option A shows the correct syntax.

This XML document is well-formed because it has a proper XML declaration, a single root element (), all tags are properly nested, and every opening tag has a corresponding closing tag. No attributes are without quotes, and element names follow XML naming rules.

This is NOT a well-formed XML document because it lacks a single root element. XML documents must have exactly one root element that contains all other elements. Here we have four sibling elements (, , , ) at the top level.

XML attribute values MUST always be enclosed in quotes (either single or double quotes). This is a strict requirement in XML syntax. Unquoted attributes will cause parsing errors. For example: is correct, but is invalid.

XSL stands for eXtensible Stylesheet Language. It's a family of languages used to transform and render XML documents. XSLT (XSL Transformations) and XSL-FO (XSL Formatting Objects) are parts of the XSL family. The other options are incorrect expansions.
