Jerry wrote the following code and connected the circuit as shown below. What the output will be?

void setup() {
  pinMode(13, OUTPUT);
}

void loop() {
  digitalWrite(13, HIGH);
  delay(1000);
  digitalWrite(13, LOW);
  for (int i = 0; i < 3; i++)
    delay(500);
}

LED will ON for 1 Second and Turn OFF for 1.5 Sec. in a loop
LED will ON for 1 Second and Turn OFF for 2 Sec. in a loop
LED will be OFF for 1 Second and Turn ON for 1.5 Sec. in a loop
