Which of following are correct?
a, You can directly run the garbage collector whenever you want to
b, You can directly run the garbage collector whenever you want to, but you can not directly free the memory allocated by an object.
c, The garbage collector informs your object when it is about to be garbage collected.
Thank you for any suggestion!

I think c) is the answer.
Since you can never directly run GC, a) and b) are wrong

c is obviously right because of the mark and sweep algorithm that the gc uses.
I agree. Here's the link:
