From Whizlabs,



My answer for it is C since s refer to other object(Hello World) not the object created on line 1, so the object is eligible to collection.

Am I right? Please help me to confirm.

Thank you.

Yes you are right . C is the correct answer.

One more thing...K&B book states garbage collection with strings is not included in exam.
