The population in this scenario would be all registered voters in the community as the party would be interested in knowing the opinion of the entire voting population, not just the ones who responded to the survey. The 1500 registered voters who received the survey are simply a sample from the population. Therefore, the population of interest is D, all registered voters in the community.
