You are an enterprise application developer. The data access layer of an application contains the following code segment. (Line numbers are included for reference only.)

01 static public List<Employee> GetEmployees()
{
02 List<Employee> employees = new List<Employee>();
03 using (SqlConnection cnn = new SqlConnection(_cnnStr))
{
04 SqlCommand cmd = new SqlCommand(“GetEmployees”, cnn);
05 cnn.Open();
06 DataSet ds = new DataSet();
07 SqlDataAdapter da = new SqlDataAdapter(cmd);
08 da.Fill(ds);
09 foreach (DataRow row in ds.Tables[0].Rows)
{
10 Employee emp = new Employee();
11 emp.ID = Convert.ToInt32(row[“Id”]);
12 emp.Name = Convert.ToString(row[“Name”]);
13 employees.Add(emp);
14
}
15
}
16 return employees;
17
}

You review the code segment and discover that it takes a long time to execute. You need to modify the code segment to improve the performance.
What should you do?

A.
Create a SqlDataReader object.Iterate through a DataReader object to populate the employees list.

B.
Fill a DataTable object by using a DataTable.Load method.Iterate through the DataTable to populate the employees list.

C.
Fill a DataTable object by using a SqlDataAdapter object.Iterate through the DataTable to populate the employees list.

D.
Fill a DataTable object by using a DataTable.Load method.Create a DataTableReader object from the DataTable.Iterate through the DataTableReader to populate the employees list.
