Answer: C) It changes from a student’s perspective to her teacher’s perspective.
Explanation: In the given excerpt we can see the description of how Jenna (a student) spilled water across the lab table, ruining her notes, and how she felt like she was about to cry. Then we see the reaction of the teacher, who saw the mess and thought that no one in that group wanted to do the chemistry experiment. So, as we can see, the perspective changes from as student's perspective to her teacher's perspective.
