B
Caching is not done on frequently changing data. Caching is usually done on fixed data so we need to go to end server.. so correct answer is B.
I think the question ask about the characteristic of edge locations, not the benefit of edge location. So answer “C” seems to be more appropriate than “B”.
“C” is wrong, “B” is correct.
