I may be wrong but I am pretty sure it is future generations, best of luck.
Answer: C. future generations
Explanation:
The "word" posterity means "future generations" in the context of this excerpt. It talks of the American Government as a tradition to be passed on to future generations intact which, unfortunately, is not what really happens.
"Posterity" originated from Latin, "posterus", meaning "following". An example with the word would be:
"We shall preserve his unique artwork for posterity."
