Answer:
A
Step-by-step explanation:
The speaker says 'he will not go behind his father saying' which means his neighbor does not like to change, very much adamant in adhering to tradition. In the entire poem, the neighbor twice repeats 'Good fences make good neighbors' , which the neighbor is very much strict in erecting wall rather than mending it. For the neighbor, wall symbolizes privacy which mean distance, a distance which helps make relation compact and better. The more the wall is high and compact, the better is relation between neighbors. This is what speaker thinks of the neighbor.
