The nonresponse rate is the proportion of individuals who refused to answer the survey or could not be reached. In this case, the total number of registered voters surveyed was 200, and 60 said Sullivan, 60 said Mossman, so the response rate is 60 + 60 / 200 = 60%.

Therefore, the nonresponse rate is 100% - 60% = 40%, which is the proportion of individuals who refused to answer the survey.

Thus, the correct answer is B, 40%.
