Given the code:

public class CheckingAccount {  
           public int amount;  
     
           public CheckingAccount(int amount) {  
                   this.amount = amount;  
           }  
     
           public int getAmount() {  
                   return amount;  
           }  
     
           public void changeAmount(int x) {  
                   amount += x;  
           }  
   }

And given the following main method, located in another class:

public static void main(String[] args) { 
           CheckingAccount acct = new CheckingAccount((int) (Math.random() * 1000)); 
           // line n1 
           System.out.println(acct.getAmount()); 
   }

Which three lines, when inserted independently at line n1, cause the program to print a 0 balance ? (Choose three.)

this.amount = 0;
amount = 0;
acct (0);
acct.amount = 0;
acct. getAmount () = 0;
acct.changeAmount(0);
acct.changeAmount(-acct.amount);
acct.changeAmount(-acct.getAmount());
