You create an application by using the Microsoft .NET Framework 3.5 and Microsoft ADO.NET. The application connects to a Microsoft SQL Server 2005 database.

You write the following code segment.

string query = "Select EmpNo, EmpName from dbo.Table_1;select Name,Age from dbo.Table_2";
SqlCommand command = new SqlCommand(query, connection);
SqlDataReader reader = command.ExecuteReader();

You need to ensure that the application reads all the rows returned by the code segment.

Which code segment should you use?

A.
while (reader.NextResult())
{
Console.WriteLine(String.Format("{0}, {1}",reader[0], reader[1]));
reader.Read();
}

B.
while (reader.Read())
{
Console.WriteLine(String.Format("{0}, {1}",reader[0], reader[1]));
reader.NextResult();
}

C.
while (reader.Read())
{
Console.WriteLine(String.Format("{0}, {1}",reader[0], reader[1]));
}
reader.NextResult();
while (reader.Read())
{
Console.WriteLine(String.Format("{0}, {1}",reader[0], reader[1]));
}

D.
while (reader.NextResult())
{
Console.WriteLine(String.Format("{0}, {1}",reader[0], reader[1]));
}
reader.Read();
while (reader.NextResult())
{
Console.WriteLine(String.Format("{0}, {1}",reader[0], reader[1]));
}
