The data and analysis are structured to enhance understanding of this relationship.**Task:**a. Construct a scatter plot for RPM and torque.**Scatter Plots:**Four scatter plot options are provided, labeled A, B, C, and D. Each plot presents torque on the vertical axis and RPM on the horizontal axis, with the following observations:- **Plot A:** Shows a downward trend, indicating that torque decreases as RPM increases.- **Plot B:** Exhibits a scattering of points without a clear trend.- **Plot C:** Demonstrates an upward trend, suggesting that torque increases with higher RPM.- **Plot D:** Illustrates a parabolic pattern where torque initially increases with RPM, reaches a peak, and then decreases.These visual representations offer insights into how engine speed correlates with torque, aiding in the prediction of engine performance characteristics.
