To find out how many degrees should be represented in the pie graph, we can use the formula:

(degrees in sector) = (percentage of data) x 360

First, we need to find out what percentage of the class does three hours of homework each day:

8 classmates out of 24 is equivalent to:

8/24 = 1/3 or 33.33%

Now we can calculate the degrees in the sector:

(degrees) = (0.3333) x 360 = 120 degrees

Therefore, the answer is choice letter C, which represents 120 degrees.
