I'm taking a test and have to guess the right answer to the question after the article. Article: When shopping in a store, I met a boy. When I saw him waving his hands excitedly in the air and shouting in a loud voice, " Mommy, I'm here," I knew he was mentally challenged. I asked his name and he said proudly, " My name is Denny and I'm shopping with my mother." "Wow," I said, " That's a cool name. How old are you, Denny?" " How old am I now, Mommy?" he asked his mother. " You're fifteen years old, Denny; now be a good boy and let the man pass by." I continued to talk to Denny for several more minutes about summer, bicycles and school. _ Denny's mom thanked me for talking with her son. She told me that most people wouldn't even look at him, let alone talk to him. I told her that it was my pleasure and then I said, " There are plenty of red, yellow, and pink roses in the garden, however, 'Blue roses'are very _ and should be appreciated for their beauty and distinctiveness . Denny is a 'Blue ses'and if someone doesn't stop and smell that rose with their heart and kindness, then they've missed a chance to appreciate the beauty." She was silent for a second, and then went away with tears in her eyes. Question: What's wrong with the boy? Options: A: He didn't know his name and age B: There was something wrong with his mind C: He lost his way D: He couldn't find his mother.
