B

semiconductors increases and of metals decreases.

C

in both metals and semiconductors increases

D

in both metals and semiconductor decreases

Text Solution

Verified by Experts

The correct Answer is:
B
Semiconductors having negative temperature coefficient of resistivity whereas metals are having positive temperature coefficient of resistivity with increase in temperature the resistivity of metal increases whereas resistivity of semiconductor decreases.
