Read the paragraph from a personal narrative.

1. It may have seemed like an ordinary day to everyone else, but to me, it couldn't have been further from it.
2. Today was my first day working as a waitress at Pete's Pizza Haven, and I could not have been more excited.
3. In fact, I was so excited that I rushed to get ready much faster than I typically do.
4. "I'm ready to go!" I shouted, bouncing down the stairs and flying into the kitchen, where my mom was making breakfast.
5. "I have so much to learn and don't want to be late," I declared for emphasis. My mom just grinned and placed a steaming plate of eggs before me.

Which should be added after sentence 6 to most effectively move the plot forward?

A. The excitement of my new job started to wane, and I began to reconsider if this was truly how I wanted to spend my summer.
B. Once I arrived, I quickly learned that my job would also entail wiping tables, mopping floors, and washing dishes.
C. I gulped down my food, grabbed my bus card, and pecked my mother on the cheek as I raced out the door.
D. As I think back on my first job, I remember the many mistakes I made and the important lessons I learned.
