Which one of the following is the output of the above code?

private static int DoComputation(int start){
  int sum = 0;
  for (var value = 1; value <= start; value++){
    sum += value;
  }
  return sum;
}
public static void Main(){
  int sum = 0;
  Task<int>[] taskArray = {
    Task<int>.Factory.StartNew(() => DoComputation(3)), Task<int>.Factory.StartNew(() => DoComputation(4))
  }
  ;
  for (int i = 0; i < taskArray.Length; i++){
    sum += taskArray[i].Result;
  }
  Console.WriteLine($"{sum}");
  Console.ReadLine();
}
