The middle 50% of the scores are represented by the IQR (the range between the 25th and 75th percentiles). We know that Q1 = 39 and IQR = 105. To find the 75th percentile, we can add 105 to Q1, giving us 144. Therefore, the middle 50% of scores are between 39 and 144, which corresponds to choice C.
