Can someone please help me out with this? I think Part A would be either A or B and Part B is probably either A or D. Title of short story: The Treasure of Lemon Brown

Part A: How does Greg and Lemon Brown’s relationship develop throughout the text?
A. Greg and Brown look out for one another by the end of the text
B. Greg and Brown develop a father-son relationship
C. Greg and Brown learn to tolerate each other
D. Greg and Brown become beat friends

Part B: Which quote from the text best supports the answer to Part A?

Thank you in advance
