The temperature dependence of resistances of \( \mathrm{Cu} \) and undoped \( \mathrm{Si} \) in the temperature range \( 300-400 \mathrm{~K} \), is best described by:
(A) Linear decrease for \( \mathrm{Cu} \), linear decrease for \( \mathrm{Si} \).
(B) Linear increase for \( \mathrm{Cu} \), linear increase for \( \mathrm{Si} \).
P
(C) Linear increase for \( \mathrm{Cu} \), exponential increase for \( \mathrm{Si} \)
(D) Linear increase for \( \mathrm{Cu} \), exponential decrease for \( \mathrm{Si} \)
