You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to develop an application. A file named books.xml contains the following XML.
<bib>
<book title="Programming in Unix" year="1992">
<author>Author1</author>
<author>Author2</author>
<author> Author 3 </author>

book. The text content of the element must contain the title of the book.
You need to create a query that generates the new XML result. What should you do?
- A. XDocument document = XDocument.Load("books.xml");
var query = from node in document.DescendantNodes()
where node.ToString() == "book"
select new XText("BookTitle" + node.ToString()); - B. XDocument document = XDocument.Load("books.xml");
var query = from node in document.DescendantNodes()
where node.ToString() == "book"
select new XElement("BookTitle", node.ToString()); - C. XDocument document = XDocument.Load("books.xml");
var query = from node in document.Descendants()
where node.Name.LocalName == "book"
select new XElement("BookTitle").Value = node.FirstAttribute.Value; - D. XDocument document = XDocument.Load("books.xml");
var query = from node in document.Descendants()
where node.Name.LocalName == "book"
select new XElement("BookTitle", node.FirstAttribute.Value);
