The major difference between a pure semiconductor and a pure metal is that
A
metals are harder than semiconductor
B
while resistance of metals decrease with temperature , the reverse is the case for semiconductor
C
the resistance of metals increases with temperature, while for semiconductors, it is the reverse
D
metals have forbidden gaps while semiconductors have not
Verified Correct Answer: C.
