The answer to this question is Option C.
As stated in the problem, both programs being Math Master (75% to 87%) and Excel (73% to 81%) increased, therefore, meaning they are both effective as the average test scores increased. However, Math Master had a higher average test score increase compared to Excel, meaning it is even more effective.
Hope this helps :)
