NO.5 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.

}
Each application uses a custom configuration section to store department-specific values in the
application configuration file as shown in the following code.
<Department>

<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?

protected override void DeserializeElement(
XmlReader reader, bool serializeCollectionKey) {
Department dept = new Department();
dept.name = ConfigurationManager.AppSettings["name"];
dept.manager =
ConfigurationManager.AppSettings["manager"];
return dept;
}
}

XmlReader reader, bool serializeCollectionKey) {
Department dept = new Department();
dept.name = reader.GetAttribute("name");
dept.manager = reader.GetAttribute("manager");
}
}
C. public class deptHandler : IConfigurationSectionHandler {
public object Create(object parent, object configContext,
System.Xml.XmlNode section) {
Department dept = new Department();
dept.name = section.SelectSingleNode("name").InnerText;
dept.manager =
section.SelectSingleNode("manager").InnerText;
return dept;
}
}
D. public class deptHandler : IConfigurationSectionHandler {
public object Create(object parent, object configContext,
