The chart shows the number of cars sold per week at a car dealership during the month of June.

Salesperson Week 1 Week 2 Week 3 Week 4
Tim 4 8 2 1
Geena 1 2 7 1
Rafael 2 1 5 4
Sonny 4 1 1 10

How should the data be displayed to make the most convincing argument that sales improved each week?

A. A bar graph of the total car sales per week
B. A box-and-whisker plot of Sonny's sales per week
C. A line graph of each salesperson's sales per week
D. A circle graph showing how many cars each person sold during the month

I think it's either A or B, but I really can't decide.
