Not exactly sure, but I think the answer would be D as the population of interest is the one being polled, which is 58% of the registered voters.
I think the answer is D because its the number of how many people were intrested or how many voters interviewed.
The professor is nterested in the registered voters in the district, and it trying to make some inferences on that group, answer A.
What really should be the population of interest is those of the 450,000 registered voters who will actually vote. Polls are not very good at sampling or predicting the people who people who actually vote, although some try.
I agree with Bob that A is the best answer among those options.
