Is the line you quoted discussing "why mathematics can be considered a language"?
If not, why are we looking there? The test-writers, when they are creating trap answers, need some of those answers to be tempting, so they grab words/phrases that were used somewhere in the passage so that the answer has a familiar ring.
In order to counter this, we are trying to develop a process in which we first find the answer in the passage, lock in on that answer, and don't let ourselves budge from that answer when we start hearing familiar wording in other answer choices that comes from elsewhere in the passage.
Lines 18-24 say that there is a debate about what language is or does: one possible interpretation is that it's purely a matter of agreed-upon conventions. The author never endorses that theory. She just describes to us that it's gaining wider acceptance among linguists. We don't even know if a majority of linguists accept this possible interpretation of language. We only know that a growing number do.
But since we're being asked, "According to the passage, why is mathematics considered a language", it seems like lines 3-6 provide a direct answer to that question.
Looking at line 21-24, where we're not even discussing mathematics, we'd have to do a lot of off-the-page speculation to assume that "Math is considered a language because it relies on agreed-upon conventions".
