Answer options:
Assume that garbage collection runs and all elligible objects are collected and finalized.
A It does not compile due to incorrect signature of the finalize method.
B It compiles but no text is written when it runs due to incorrect signature of the finalize method.
C Before "exiting" is written, 2 messages from finalize will be printed.
D Before "exiting" is written, 3 messages from finalize will be printed

Which one would be the answer?

I think the answer should be option C. There are two objects which are eligible for garbage collection.
They are the ones which are generated when i=0; and i=1; the object created when i=2; has reference t and obj.

Hope that helps you.

Hi Vidyavathi,

I think none of the answers are correct. Even with the assumption that the garbage collector is run, the 2 messages could be printed before or after the "exiting".

Joyce is correct. I have just compiled and run the program to get:

Assume we face a question like the one above, aren't we suppose to go with option (c) since thats the only possibility ?

No, you write to the author of the mock exam and tell them they're wrong.
