Two rods of the same length and areas of cross-section `A_1` and `A_2` have their ends at the same temperature. `K_1` and `K_2` are the thermal conductivities of the two rods. The rate of flow of heat is same in both the rods if-

A

`(A_(1))/(A_(2))=(K_(1))/(K_(2))`

B

`(A_(1))/(A_(2))=(K_(2))/(K_(1))`

C

`A_(1)A_(2)=K_(1)K_(2)`

D

`A_(1)K_(1)^(2)=A_(2)K_(2)^(2)`
