Considering the confidence interval for the previous Gallup poll which of the following statements is true? *** i cant seem to get the interpretation right HELP PLEASE***

A.We can state with 95% confidence that between about 66.97% and 67.03% of American adults strongly agree with the statement.

B.Since the confidence interval (from 64% to 70%) is appropriately small, we can state with 95% confidence that 67% of American adults agree with the statement.

C.Our confidence that 67% of Americans strongly agree with the statement is at least 92%, but no more than 98%.

D.We can state with 95% confidence that between about 64% and 70% of American adults strongly agree with the statement.

E.Because the interval between 64% and 70% doesn't contain 95%, we can't be confident in this statistic.
