Lynn wants to predict how much fuel her car will use based on its speed. She drove her car $100\,\text{km}$ at each of the speeds below, and she measured how much fuel was used at each speed. Her data is summarized in the table below.

:-- | --: | --: | --: | --: | --: | --: | --: | --: | --: | --: |
**Speed (km/hour)** | $20$ | $40$ | $60$ | $80$ | $100$ | $120$
**Fuel used (liters)** | $13.0$ | $8.0$ | $5.9$ | $7.0$ | $8.3$ | $9.9$
**All of the scatter plots below display the data *correctly*, but which one of them displays the data *best*?**
*By convention, a good scatter plot uses a reasonable scale on both axes and puts the independent variable on the $x$-axis.*
