The current and voltage of the new ultrathin CIGS solar cells vary based on temperature. The graph shows the current, in miliamps per square centimeter (mA/cm²), and voltage, in volts (V), at various temperatures, in degrees Kelvin (K). Which of the following best estimates the rate of change of voltage, in volts per degree Kelvin (V/K)? A. 0.58–0.74 / 400–0
B. 0.58–0.74 / 400–300
C. 400–0 / 0.58–0.74
D. 400–300 / 0.58–0.74​
