Answer:
D)
Step-by-step explanation:
I think it is D) because for A), he says nothing about the way the house looks. For B), the length of time it took to open the door is not important, and the paragraphs aren't about that. For C), there is nothing about the death of Davie's parents mentioned. D) is the only logical answer, plus it said how he thought he was a servant, but sees at the end that it is his uncle.
