With increase in temperature, the electrical conductivity would
increase in metals as well as in intrinsic semiconductor
increase in metals but decrease in intrinsic semiconductor
decrease in metals but increase in intrinsic semiconductor
decrease in metals as well as in intrinsic semiconductor
Answer: Option
Explanation:

Increase in temperature causes resistivity of metals to increase and resistivity of intrinsic semiconductors to decrease.

Conductivity is reciprocal of resistivity.
