The presence of F1F1F1S1 indicates a sulfonic acid (-SO3H) and F1F1F1F1^- is a strong, basic fluoride ion. Therefore, this is an acid/base reaction. The reaction between a strong acid and a strong base is typically exothermic, which eliminates choices B and D. The negative sign for F1F1F1S1F1F1F10H indicates that the reaction releases heat, which supports choice C. Therefore, the correct answer is C.
