Kai promised to repair Krystal's car on Thursday. After picking up the necessary part at a junkyard, he discovered he could not do the job after all and that the junkyard would not buy back the part. Krystal does not know about these developments. However, she thinks Kai will be finished with her car sometime today. What should Kai do?
A. Try to repair the car even though he does not really know how.
B. Try to repair the car so he can at least get his money's worth out of it.
C. Call Krystal to inform her of the problem, and recommend a reputable repair shop.
D. Fake an emergency and contact Krystal on Monday.
E. Stall for time to read up on car repairs so he can practice on Krystal's car.
