Harry built the following circuit. Which of the following statements are true about the circuit?

const int button1Pin = 4;
const int button2Pin = 5;

void setup() {
  Serial.begin(115200);
  pinMode(button1Pin, INPUT);
  pinMode(button2Pin, INPUT);
}

void loop() {
}

Pressing button 1 will transition pin 4 from LOW to HIGH.
Pressing button 2 will transition pin 5 from LOW to HIGH.
Pressing button 2 will transition pin 5 from HIGH to HIGH.
Pressing button 1 will transition pin 4 from LOW to LOW.
