Answer:
a. give what they regard as the socially correct response.
Explanation:
A poll is a survey in which a group people are asked about their opinion on a particular matter and it is used to try to understand what most people think using a representative sample. For a poll to be accurate, it is needed that people express what they truly believe about a topic. Because of that, the answer is that the accuracy of polling is diminished when respondents give what they regard as the socially correct response as they are not actually saying what they really think which affects the result of the poll.
