To determine the width of each class, we need to find the difference between the upper limit of a class and the lower limit of the same class. For example, the width of the class 1-5 can be found by subtracting 5 (the lower limit) from 1 (the upper limit), which gives 4. Similarly, the width of the class 6-10 can be found by subtracting 10 (the lower limit) from 6 (the upper limit), which gives 4. We can repeat this process for all the classes and find that the width is 4 for each of them except for the first class, which has a width of 5. Therefore, the answer is B (5).
