Answer:
The theme of the poem is:
A. Everything in nature comes from the same place.
Step-by-step explanation:
"Wind, Water, Stone" is a poem by Octavio Paz. The speaker describes several ways in which the three elements mentioned in the title interact and, in some ways, even become one another. The poem plays with the idea that the different elements are able to influence each other, change each other, and change themselves. What the speaker means is that they are all the same thing: they are all nature. There is no distinction between them in the end. That is what the last stanza shows:
Each is another and no other:
crossing and vanishing
thought their empty names:
water, stone, wind.
Their names are empty because they mean nothing. There is no reason to call stone stone or water water because there is no distinction between them.
