Answer:
The answer is B Two Rare And Valuable Pennys
Explanation:
It couldn't have been A because the first penny has nothing to do with stamping
and it couldn't be C because the second penny doesn't have anything to do with WW2
and it couldn't be D because it barely skims the surface of that topic.
Now of course all of those are mentioned, but the one that stands out the most, and is most relevant is B.
So logically the answer is B.
