Answer:
D) My father owns a small store, and I have worked very hard there for many years.
Explanation:
Option A is wrong for there is no evidence in the passage that the shop was a hardware store.
Option B is also wrong as the duration of her working there is just put as "quite a while".
Option C is wrong as there is no indication of the name of the store nor the duration of her working there.
The correct option is option D, for it correctly mentions the details of sentence (8) such as "small store" and "many years". Thus, the right answer is
My father owns a small store, and I have worked very hard there for many years.
