B.95% of sample proportions will fall between the lower bound and the upper bound.

C.There is a 95% chance that the true value of the population proportion will fall between the lower bound and the upper bound.

D.One has 95% confidence that the interval from the lower bound to the upper bound actually does contain the true value of the population proportion.
