Answer:
D.) The twin getting a C is using a Fixed Mindset.
Explanation:
According to Dr. Dweck, the terms growth mindset and fixed mindset are the ones that explain the beliefs people have about intelligence and the learning process. In a growth mindset, it is the case that a student actually believes that he or she can become smarter. That same student, in this case, understands that such achievement will come through effort; making them to be willing to put effort and time into learning more. A fixed mindset is actually the idea that "there is no point in trying" because things won't change. And that mindset is what needs to change for there to be any growth.
