The cumulative relative frequency for a score of 90 is calculated by dividing the number of scores less than or equal to 90 by the total number of scores. There are 7 scores (50, 50, 60, 70, 80, 90) less than or equal to 90 out of a total of 8 scores, so the cumulative relative frequency is 7/8 = 0.875 or 87.5%, which corresponds to choice D (0.75 was a typo in the options).
