Answer:
B). Candace's data is on a graph.
Step-by-step explanation:
As per the given description, Candace is the student who is most likely to win the science fair as the graphic presentation would appeal to the audience visually and provide them vivid and clear representation of the data. While the way other two students are presenting data are least likely to convey the intended information or elicit intended response or understanding from them as the audience will have to assess and analyze the data table or list. But graphic representation would present the complex and detailed data in a clear and comprehensive manner. Thus, option B is the correct answer.
