It's c got it right

After everyone had gone, my mother said to me. "You want to be the same as American girls on the outside." She handed me an early gift. It was a miniskirt in beige tweed. "But inside you must always be Chinese. You must be proud you are different. Your only shame is to have shame."And even though I didn't agree with her then, I knew she understood how much I had suffered during the evening's dinner. It wasn't until many years later - long after I had gotten over my crush on Robert - that I was able to fully appreciate her lesson and the true purpose behind our particular menu. For Christmas Eve that year, she had chosen all my favorite foods.

Why does Tan end the essay by telling the reader that her mother had chosen her favorite foods?

to contrast the way Amy feels about the food and the way her mother feels about it
to show that her mother only cares about preserving her Chinese culture
to contrast her own descriptions of the food with how she really feels about the food
to show that her mother is sorry for what she put Amy through
