To find the response rate, we need to divide the number of completed surveys by the total number of surveys that were not returned due to the wrong address. The total number of surveys that were not returned due to the wrong address is 400 - 30 = 370. So, the response rate is 120/370 = 0.324 or 32%. Rounded to the nearest whole number, the response rate is 32%. Therefore, the correct answer is (C) 32%.
