Analyze the following code and choose the best answer:

public class Foo {
private int x;

public static void main(String[] args) {
​Foo foo = new Foo();
​System.out.println(foo.x);
}
}


▸ Since x is an instance variable, it cannot be directly used inside a main method. However, it can be accessed through an object such as foo in this code.

▸ Since x is defined in the class Foo, it can be accessed by any method inside the class without using an object. You can write the code to access x without creating an object such as foo in this code.

▸ Since x is private, it cannot be accessed from an object foo.

▸ You cannot create a self-referenced object; that is, foo is created inside the class Foo.
