Choose the XML block that shows which content will be written to the C:Meeting.xml file?

You work as the application developer at Domain.com.
You are working on a component which serializes the Meeting class instances.
The definition of the Meeting class is as follows:
public class Meeting {
private string title;
public int roomNumber;
public string[] invitees;
public Interview(){
}
public Interview (string t){
title = t;
} }
You configure the following procedure for your component:
Meeting myMeeting = new Meeting(“Objectives”);
myMeeting.roomNumber=20;
string[] attendees = new string[2]{“Amy”, “Ally”};
myMeeting.invitees = attendees;
XmlSerializer xs = new XmlSerializer(typeof(Meeting));
StreamWriter writer = new StreamWriter(@”C:Meeting.xml”);
xs.Serialize(writer, myMeeting);
writer.Close();
You want to find out which XML block will be written to the C:Meeting.xml file when the procedure is executed.
