B)  

55.5

Step-by-step explanation:The interquartile range is the third (upper) quartile of a data set minus the first (lower) quartile. Here, the median is 60, dividing the data set into a lower half below the median and an upper half above the median. Each of these halves contains four data values. The upper quartile is the number midway between 80 and 85, or 82.5. The lower quartile is the number midway between 19 and 35, or 27. The interquartile range is 82.5 - 27 = 55.5.
