Hi Lunsandy,
First, let's look at what we're asked to do in this question: strengthen a specific conclusion. The conclusion we're trying to strengthen here is that all human language has an essential link to the things it denotes, i.e. there is something essentially cat-like about the word 'cat' itself. The passage spends most of its words explaining the arguments in favor of the alternative conclusion, that words are merely arbitrary and only derive meaning from human agreements. Since the passage sets up the two conclusions to be mutually exclusive and the only two possible, weakening the conclusion the passage supports would also strengthen the conclusion in question 23, and vice versa.
If answer choice (A) were true, and one human language that developed independently from another both use the same categories for physical objects, then the idea that language emerges from mutual assent is weakened, and the idea that there is a fundamental link between language and what it describes is strengthened, as the two languages have a striking similarity despite emerging independently.
Answer choice (C) doesn't work because it deals only with speakers of the same language; if anything, this weakens the conclusion we are trying to strengthen. In fact, (C) is almost a given: by definition, it's expected that people who speak the same language would use the same categories of physical objects, otherwise it wouldn't be the same language!
Hope this clears things up!
