The resistivity ( $\rho$ ) of a semiconductor varies with temperature. Which of the following curves represents the correct behavior?

A
$Graph of resistivity $$\rho$$ versus temperature $$T$$ showing a straight line increasing upward from left to right after a small positive temperature intercept.$
B
$Graph of resistivity $$\rho$$ versus temperature $$T$$ showing a curved increase upward from left to right, becoming steeper at higher temperature.$
C
$Graph of resistivity $$\rho$$ versus temperature $$T$$ showing a decreasing curve that falls rapidly first and then gradually flattens as temperature increases.$
D
$Graph of resistivity $$\rho$$ versus temperature $$T$$ showing a straight line decreasing downward from left to right toward zero as temperature increases.$
