Hello!!!
Honestly I would have chosen Doc B but its up to you.
doc A: This quote talks more about heritage and the territoriality and its relation to identity which was in the past but still affects the future (in a good way)
doc B: This quote talk more about the cult of memory, when history does more harm than good and it also talks about territory,power and memory (which people tries to forget or doesn't like to talk about it. Example: the Bosnian War.
I hope that this has helped you ♥
