Evidence (B.) is the answer
Hi. You did not enter the text to which this question refers, which makes it impossible for it to be answered. However, and I will try to help you as best I can.
To answer this question, you will need the text it is related to. As stated in the question, you must present two sentences where the author is reflecting on the experiences he has had. In this case, you will need to find, within the text, the moments when the author shows thoughts about his experiences, where he presents what he learned and how these experiences were positive or negative for his life and how this contributed to the story that it's counting, that is, you shouldn't look for the experiences themselves, but how they impacted the author.
Answer:
<em>Well, studies show that spending our hard-earned money on experiences actually makes us happier. They bring more lasting joy, often because they can be shared with others in the moment, as well as offering shareability on social media. In short, experiences are a way to build community and to deepen relationships.</em>
