D. "I have a dream that enough is enough!" Yolanda declared at March for Our Lives.
Step-by-step explanation:
The correct answer is option D. Yolando makes it known in this quote that she is fed up with guns, and "enough is enough." Yolando, obviously being related to Martin Luther King, uses "I have a dream" to make her point come across as more powerful and important. Another piece of evidence is that she attended March for Our Lives, which is students against gun violence.
