Answer: A

Explanation:

The class intervals 11.5-13.5, 13.5-15.5, 15.5-17.5, and 17.5-19.5 are appropriate for representing the given data set in a histogram. These intervals cover the entire range of the data, ensuring each data point falls within a specific interval, and they are consistent in width, which is crucial for accurate histogram representation.
