First, we cancel out C, it specifically said that she wasn't aplied. Lazy? maybe... She obviously isn't very studious but that does not automatically means lazy. Serious? Well... It never really says anything about seriousness. Honestly, it is a pretty cr*ppy question but hey, that's English class for ya. The only one that works is D. Diligent. Now, it might be lazy, because it says that she never studies, but the paragraph ends with her finding a new passion and how she loves to cook. So that is not particularly lazy. Tell me if I was right or not, and I hope this helped.
