Answer:
The correct option is this: THE CROWD IS MOVED BY THE STUDENTS' COMPASSION.
The address read by Allison Gibson, one of the student representative conveyed the feeling of the student to the crowd. The content of the letter talks about the students' support. The crowd was momentarily carried away by the emotion of compassion that was expressed by the letter and that was why it took them sometimes before they can greet the message with loud cheering.
