you create a microsoft asp net application by using the framework..., Appendix,

Question:
You create a Microsoft ASP.NET application by using the Microsoft .NET Framework version 3.5. You store the following XML fragment in a string variable named xmlFragment in a Web form.

<Products> 
<Product price="12" />
 <Product price="24" /> 
<Product price="56" /> 
<Product price="89" />
 </Products>

You need to display the value of the price attribute for each Product element that is contained in a ListBox control named lstPrices. Which code segment should you use?

A XElement element = XElement.Parse(xmlFragment); 
var lst = from prods in element.Elements("Product") select prods.Attribute("price").Value; lstPrices.DataSource = lst; lstPrices.DataBind(); 
B var doc = new XmlDocument(); doc.LoadXml(xmlFragment); 
foreach (XmlNode price in doc.SelectNodes("//price")) {
 lstPrices.Items.Add(price.ToString()); } 
C var reader = new XmlTextReader(new StringReader(xmlFragment));
 XNode node = XElement.ReadFrom(reader); 
var lst = from prods in node.ElementsAfterSelf("Product") select prods.Attribute("price").Value;
 lstPrices.DataSource = lst; lstPrices.DataBind(); 
D var doc = new XmlDocument(); 
doc.LoadXml(xmlFragment); 
foreach (XmlNode price in doc.SelectNodes("Products/price")) {
 lstPrices.Items.Add(price.Value); }
