Read the excerpt from the general prolgue to the canterbury tales.

her headkerchiefs were of the finest weave,
ten pounds and more they weighed, i do believe,
those that she wore on sundays on her head.
her stockings were of the finest scarlet red,
very tightly laced; shoes pliable and new.
bold was her face, and handsome; florid too.

which details suggest that the narrator may be unreliable?

i do believe which means that the narrator is unsure when you say that that means you are unsure about something

You are looking for a detail that is not to be believed, making the narrator (the person speaking) to be unreliable.  So as you read, which detail does not fit or is not believable?  At the beginning, it states that the headkerchiefs were ten pounds.  Think of a handkerchief, which is a very thin, light material.  Even if the material used on the head where thicker, could they really be ten pounds?  All the other details are plausible, meaning they could happen.

in paragraph 6 of "sinners in the hands of an angry god" by jonathan edwards, he talks about how doing good things alone will not save men from going to hell because they're at the mercy of the will of god. "spiritual reform" provides men with a false sense of safety.

i think it may be b, i'm not exactly too sure on this. but b seems to make more sense.
