All of these options are true. Bars of a frequency distribution should be touching each other unless there is a category with zero frequency to indicate that there is a gap in the data. They should also be centered on the score value to accurately represent the frequency data for that particular category. Finally, the bars should extend horizontally from the lower real limit of the score value to the upper real limit to show the range of possible scores that fall within that category.
