Read the following excerpt from the poem "mending wall" by robert frost:

and eat the cones under his pines, i tell him.
he only says, 'good fences make good neighbors.'

b. he resents the neighbor's insistence that he rebuild the fallen wall.
c. he is relieved that the neighbor wants to continue maintaining the wall.
d. he is annoyed that his neighbor insists on maintaining an unnecessary wall.
