Assume you have three separate .java source files

In Base.java: public class Base {} -------------------------------------------- In Derived.java: public class Derived extends Base {} -------------------------------------------- In Use.java:

public class Use { public static void main(String[] args) { Base b = new Base(); Derived d = new Derived(); // Will this following assignment generate an error? b = d; } } -------------------------------------------- Which of the following is true if we try to compile the 3 files and run the Use class?

Question 1 options:

	The program won't compile unless you change the last line of Use.java to include a cast: b = (Base) d; and then the program will compile but will have a run time error when the assignment into b is executed.
	There is no way to assign d into b without a compiler error.
	The program won't compile unless you change the last line of Use.java to include a cast: b = (Base) d; and then the program will compile and run without error.
	The program will compile and run as is without error.
