To find the number of degrees for each category in a pie graph, you need to find the fraction of the total that it represents and multiply by 360 (which is the total number of degrees in a circle). So, 8/24 simplifies to 1/3. 1/3 multiplied by 360 is 120 degrees. Therefore, the answer is choice C, 120°. In order to find the number of degrees that 8/24 represents in a pie graph, we need to multiply it by the total number of degrees in a circle (360°). 
8/24 * 360° = 120° 
Therefore, choice C is the correct answer. The other choices are not the correct calculation for this problem.
