The answer is B. Zara mentions that "the FOXP2 gene... plays a central role in the brain's language production processes, both cognitively (through pattern-mapping abilities) and physically (developing the facial muscles needed for articulating complicated sounds)." This shows that the gene controls language production, supporting (B). There is no evidence in the script supporting (A) or (C).

The 15 afflicted members of this family shared an inherited mutation of FOXP2, a gene that plays a central role in the brain's language production processes, both cognitively (through pattern-mapping abilities) and physically (developing the facial muscles needed for articulating complicated sounds).

The answer is A. Zara says, "researchers found that individuals with a certain variation on the FOXP2 gene were both faster and more accurate at doing the language task." This means participants with a particular variation of the gene did the task better, which supports (A). There is no evidence for (B) or (C).
