Hello!

You have to first find the median

74, 74, 83, 83, 83, 86, 87, 90, 92, 93, 93, 94

The numbers in the middle are 86 and 87

The average of these numbers are 86.5

The median is 86.5

This is shown in the box plot so the median is right

The lower quartile is the median of the numbers less than 86.5

74, 74, 83, 83, 83, 86

The median of these numbers is 83

The lower quartile is right

The find the upper quartile you find the average of the numbers higher than 86.5

87, 90, 92, 93, 93, 94

The upper quartile is 92.5

Since this is shown differently in the box plot the answer is upper quartile

The answer is C) upper quartile

Hope this helps!
