What happens if constructor of class N is made private?

1. Any class can instantiate objects of class N
2. Inherited class can instantiate objects of class N
3. classes within the same package as class A can instantiate objects of class N
4. Objects of class N can be instantiated only within the class where it is declared
5. None of these

If we make any class constructor private, we cannot create the instance of that class from outside the class.
