The number of classes should be chosen based on the size of the data set and the amount of detail desired. Generally, it is recommended to have between 5 and 20 classes. Having too few classes can result in a loss of information, while having too many classes can result in an overly complex display of data. Therefore, option B is the best choice as it allows some flexibility in selecting the number of classes based on the data set.
