The answer is the last choice, or D.
When you summarize, you're supposed to gather the most important points and rewrite them in a shorter and more simplified fashion. The first three choices include mostly everything you should do when writing a summary. Usually when you summarize, it's for a concluding paragraph, so writing an introductory paragraph wouldn't be it.
Dear Diary,
It’s March 29th, and the time is 8:11. As I woke up, my first thought was (name). We had an argument over coffee. It’s embarrassing to think about. Something that small made us get at each other’s throats. It’s been a few days, maybe even a week and we still have spoken to one another! Over coffee! Know you may be wondering what I’m talking about: First we meet at our favorite coffee shop, we find a cute little spot and sit. Next, I tell her I’ll try and order what she usually drinks. So, I come back and give her her coffee. Not even 5 minutes go by and she asks why her coffee tastes different. I tell her what I ordered: Black coffee with milk and sugar. Then she yells at me saying she’s lactose intolerant! How was I supposed to know! I mean sure, it’s my fault she had a bit of diarrhea, but she could’ve told me beforehand. Anyway, I’ve felt bad ever since and I don’t know how to make it up to her. I feel horrible.
