Read the passage. something there is that doesn’t love a wall, that send the frozen-ground-swell under it and spills the upper boulders in the sun, and makes gaps even two can pass abreast. this passage from robert frost’s “mending wall” emphasizes the weakness of stones the carelessness of passers-by the hostility of neighbors the power of nature

the power of nature

In the passage the speaker talks about how the ground swells due to the water in the soil freezing. It is so strong that it lifts the boulders and breaks apart the wall. The speaker's use of the word "something" and the description of how the ground, or nature, destroys the wall each year emphasizes the power of nature. 
The other choices can be eliminated because the stones don't actually break - they're just relocated. Also, there is no mention of a person in this section of the poem at all.
