B. No, it is not reasonable because the Margin or Error is 4.3% and the population proportion of 73% falls outside the sample interval of 66.3% + 4.3%

C. Yes, it is reasonable because the Margin of Error is 2.8% and the population proportion of 73% falls with in the sample interval of 66.3% + 2.8%
