Question:
You create a class library that is used by applications in three departments of your company. The library contains a Department class with the following definition.
Public Class Department
Public name As String
Public manager As String
End Class
Each application uses a custom configuration section to store department-specific values in the application configuration file as shown in the following code.
<Department>
<name>Hardware</name>
<manager>Amy</manager>
</Department>
You need to write a code segment that creates a Department object instance by using the field
values retrieved from the application configuration file.
Which code segment should you use?
 

A Public Class deptElement 
 Inherits ConfigurationElement 
 Protected Overrides Sub DeserializeElement( _ 
 ByVal reader As XmlReader, _ 
 ByVal serializeCollectionKey As Boolean) 
 Dim dept As Department = New Department() 
 dept.name = reader.GetAttribute("name") 
 dept.manager = reader.GetAttribute("manager") 
 End Sub 
 End Class 
B Public Class deptHandler 
 Implements IConfigurationSectionHandler 
 Public Function Create(ByVal parent As Object, _ 
 ByVal configContext As Object, _ 
 ByVal section As System.Xml.XmlNode) As Object _ 
 Implements IConfigurationSectionHandler.Create 
 Dim dept As Department = new Department() 
 dept.name = section.Attributes("name").Value 
 dept.manager = section.Attributes("manager").Value 
 Return dept 
 End Function 
 End Class 
C Public Class deptHandler 
 Implements IConfigurationSectionHandler 
 Public Function Create(ByVal parent As Object, _ 
 ByVal configContext As Object, _ 
 ByVal section As System.Xml.XmlNode) As Object _ 
 Implements IConfigurationSectionHandler.Create 
 Dim dept As Department = new Department() 
 dept.name = section.SelectSingleNode("name").InnerText dept.manager = _ section.SelectSingleNode("manager").InnerTex 
 Return dept 
 End Function 
 End Class 
D Public Class deptElement 
 Inherits ConfigurationElement 
 Protected Overrides Sub DeserializeElement( _ 
 ByVal reader As XmlReader, _ 
 ByVal serializeCollectionKey As Boolean) 
 Dim dept As Department = New Department( 
 ) dept.name = ConfigurationManager.AppSettings("name") "A Composite Solution With Just One Click"-
