Answer:
b). inspecting a stone wall.
Step-by-step explanation:
The lines are from Robert Frost's poem titled 'Mending Wall.' In the given lines, the speaker is examining the stone wall that has separated the two neighbors. He says that 'something...doesn't love a wall' in order to refer to nature's dislike of this wall as it leads to 'frozen ground' among two neighbors and 'make gaps...swell...burst.' Later he talks about the damage caused to the wall by the hunter's work but he would fix it again but thinks that rabbits may come 'out of hiding.' Thus, this shows that he is examining the wall. Hence, option b is the correct answer.
