In the weeks leading up to the election of a controversial public figure to political office, a polling agency conducted in-person interviews with 1000 randomly selected eligible voters. Only 35 percent of these 1000 voters said they planned to vote for the controversial candidate. However, on election day, when voters can make their selections anonymously and without having to reveal who they voted for to another person, the controversial candidate received the majority of the vote. Which of the following types of bias is most likely to have occurred in the polling agency's survey? (A) Nonresponse bias (B) Sampling bias (C) Selection bias (D) Response bias (E) Undercoverage bias
