Which C# code fragment continuously updates an object's yaw (Y rotation)?
c# transform.SetParent(null);
c# transform.localRotation *= Quaternion.Euler(0f, RotSpeed * Time.deltaTime, 0f);
c# transform.Rotate(Vector3.right, RotSpeed * Time.deltaTime);
c# transform.RotateAround(Vector3.up, RotSpeed * Time.deltaTime);
