Need help on this question. What happened last?

The first time that Ethel tried downhill skiing, she sprained her ankle. The second time she tried; she broke a ski and nearly broke her leg. After that, she was frightened to try skiing again, but her sister insisted that she come to Mt. Snow with her. This time she had a skiing lesson and really enjoyed herself. She decided she really loved skiing after all.

a. Ethel went skiing with her sister.
b. Ethel sprained her ankle.
c. Ethel took a lesson.
d. Ethel really loved skiing.

I can't decide between c and d. Thanks.

What's at the very end?
