Answer:
The best evaluation of Parvati's evidence is:
C. It is relevant and sufficient, because she gives convincing examples of how phones support classwork.
Step-by-step explanation:
Parvati's evidence is quite strong. Her argument is in favor of the use of cell phones in class. She supports it by, first, explaining how phones are similar to computers, which makes them a valuable tool to have when studying and researching. With their phones, students can access all kinds of information online to help them with their classwork. Then, she moves on to offering a personal example of how useful phones were in her civics class. Her evidence is, thus, relevant and sufficient.
