Analyze the following code:

public class Test {
public static void main(String[] args) {
Test test = new Test();
test.setAction(() -> System.out.print("Action 1! "));
}

public void setAction(T t) {
t.m1();
}
}

interface T {
public void m1();
public void m2();
}

◦ The program would work if you delete the method m2 from the interface T.
◦ The program displays Action 1.
◦ The program has a compile error because T is not a functional interface. T contains multiple methods.
◦ The program has a runtime error because T is not a functional interface. T contains multiple methods.
