Either potato choiceor agecan be represented by the bars-all two-way tables deal with categorical variables and the answer choices dealt with wording that indicated categorical displays.
The main thing is to catch that the two variables are potato choices (yes or no) and age of person (kid or adult). If you were to display this in a bar chart then potato choice could represented by the bars but age of person could also be represented by one of the bars. Your choice makes it look like only potato choice can be displayed on the x-axis but that is not true because age of person could also be displayed.
