If voters have single-peaked preferences, it means that each voter has a preferred policy position, and their utility decreases as they move away from that position in either direction. In this scenario, the median ideal policy position is preferred by a majority of voters, as it is the policy position that is closest to the preferred position of the largest number of voters. Therefore, both A and B are correct. However, it is important to note that majority rule may not always lead to the selection of the median policy under other types of preference distributions.
