As we have learnt,

 

Number of electrons or holes -

n_{e}= n_{\lambda }= AT^{3/2}e^{-Eg /2KT}
 

- wherein

Eg = Energy gap

K = Boltzmann Constant

T = Temperature in kelvin

On increasing temperature,  the number of current carried increases

 

 By increasing temperature, specific resistance of conductor increases while that of semiconductor decreases.

 


Option 1)

increases for both

Option 2)

decreases for both

Option 3)

increases, decreases

Option 4)

decreases, increases
