Linear increase for $Cu$,exponential decrease for $Si$

(A) $Cu$ (Copper) is a metal/conductor. For metals,the resistance increases linearly with temperature according to the relation $R_T = R_0(1 + \alpha \Delta T)$.$Si$ (Silicon) is an intrinsic semiconductor. For semiconductors,the number of charge carriers increases exponentially with temperature,leading to an exponential decrease in resistance,described by $R = R_0 e^{E_g / 2kT}$.
