Which concrete detail is most relevant to frederick douglass's autobiography?
a. the great house had five bedrooms, two sitting rooms, and two kitchens — one inside and one outside.
b. master daniel would not allow the older boys to impose upon me, and would divide his cakes with me.
c. mrs. lucretia told me that her favorite color was light green.
d. the man who us ashore said we were the fifth boat to land on smith's wharf that day.

B. Master Daniel would not allow the older boys to impose upon me, and would divide his cakes with me.

The behaviour of Master Daniel had a significant impact in the life of Frederick Douglass. However, the details included in the other options (the layout of the huse, Mrs. Lucretia's favourite colour and the order of the boats that landed on Smith's Wharf) are irrelevant to his life. Therefore, option B is the one that contains details that are most relevant to Douglass's life.
