To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Elements may have multiple attributes with the same name - This option is incorrect. In XML, elements cannot have multiple attributes with the same name. Each attribute within an element must have a unique name.

Option B) Quoting attribute is optional - This option is incorrect. In XML, attribute values must always be quoted. The quotes can be either single or double quotes, but they are required to specify the attribute value.

Option C) Elements may nest but not overlap - This option is correct. In XML, elements can be nested within each other, meaning an element can be a child of another element. However, elements cannot overlap or be positioned within each other.

Option D) All of the above - This option is incorrect because only Option C is true.

The correct answer is C. Elements may nest but not overlap. This means that elements in XML can be nested within each other, but they cannot be positioned or overlapped within each other.

To answer this question, we need to understand what XSL is and its components.

XSL (Extensible Stylesheet Language) is a language used for transforming XML documents into other formats, such as HTML or PDF. It consists of three main parts:

Option A) XSLT, Xpath, HTML - This option is incorrect because HTML is not one of the main components of XSL. HTML is a markup language used for creating web pages, while XSL is used for transforming XML documents.

Option B) XSLT, Xpath, ASP - This option is incorrect. ASP (Active Server Pages) is a technology used for creating dynamic web pages, and it is not one of the main components of XSL.

Option C) XSLT, Xpath, XSL-FO - This option is correct. XSLT (Extensible Stylesheet Language Transformations) is used for transforming XML documents. XPath is a language used for navigating and selecting elements in an XML document. XSL-FO (Extensible Stylesheet Language Formatting Objects) is used for defining the layout and formatting of the transformed XML document.

Option D) XSLT, Xpath, XHTML - This option is incorrect. XHTML (Extensible Hypertext Markup Language) is a markup language that combines HTML and XML, but it is not one of the main components of XSL.

Therefore, the correct answer is Option C.
