Hey there!
A prepaid tuition plan is a plan that allows you to pay the current rate of tuition now (say, years in advance), even if it's much higher than the time when the payment for tuition would actually be paid. This plan is great for anyone who wants to pay a lower price for high–cost education now (even if their kid isn't college age yet) and not have to worry about economic standing or inflation in the future that could drive the tuition prices up. 
The plan only covers tuition and other similar fees. You can not purchase books or room and board with it in advance. So, your answer should be: C. Tuition and Fees. 
Hope this helped you out! :-)
