The best replacement for the underlined word "mutate" in the sentence is **b. alter**. While "adapt" (option a) could also be a suitable choice, "alter" closely conveys the idea of changing or modifying which aligns well with "mutate." Therefore, the answer can be seen as either **b. alter** or **a. adapt**, but considering the context, **b. alter** is the most precise synonym.
