The best answer here would be the last one: "Some places have already quit lotteries," Mrs. Adams said. This is the best answer because it implies that the lottery isn't as necessary as it once was. If it was needed, the implication is that they would still be going on in the area and not forgotten or not done.
While the others hint at the same thing, they aren't the best answers because they talk about the lottery overall, but only insomuch as it pertains to the lottery itself, to fill in the details of it.
