It can be concluded that youths who had preschool education are less likely to be arrested or charged with a crime than those who did not. This is because even though the survey did not specify the percentage of youths who had preschool education, we estimated that 75% of them had attended preschool. Based on this estimate, the percentage of those who had preschool education and were arrested or charged with a crime was lower than the percentage of those who did not have preschool education and were arrested or charged with a crime. Therefore, choice C is the best answer.
