   In XML, which of the following correctly describes the relationship between elements, attributes, and nesting?

   • AAttributes and elements are interchangeable; an attribute can contain child elements, and elements can be written as attribute values.
   • BAttributes provide additional metadata about an element and are placed inside the element's start tag; elements can be nested inside other elements to form a hierarchy.
   • CAttributes are used to define the document's root element, and nesting is only allowed for text content, not for other elements.
   • DAttributes are separate elements that must appear before the parent element; nesting is achieved by placing elements side by side at the same level.
