Bthe same for all bars
Cchosen at random each time
Dequal to its own width
Answer & Solution
Correct answer: A. proportional to its value
1. Bars stand for values of categories.
2. A larger value gets a longer bar.
3. So length is proportional to the value shown.
Bars are not all equal, not random, and width is a separate matter.
