Let's visit the original text a few lines before line 46.
"blablablablabla Hopi names blablablbala. Similar to what some dude said about Apache names: blabla."
(A) is really specific, and better describes why the author mentioned Lomayayva. Note that we don't know that all Apache place names contain non-literal references, and that mentioning "Apache place names" isn't quite an "example" like Lomayayva is.
(B) describes the summarization above. A commentator called Apache names "imagist poems," which the author thinks applies to Hopi personal names.
Just be as direct as possible: WHY does the author state the words "Western Apache place names?"
Well, this phrase is used to describe "Hopi personal names." (ie Hopi names are like Apache names)
(A) seems right because the whole paragraph is about the imagery evoked in names. Like I said in the post above, though, "Apache place names" is not really used as an EXAMPLE to demonstrate references... This answer choice better describes why the author mentions "Lomayayva." This is more of an "example."
(C) points directly to the function of those words in the sentence in which they appear.
