The figure shows a system of two concentric spheres of radii `r_1 and r_2` are kept at temperature `T_1 and T_2`, respectively. The radial rate of flow of heat in a substance between the two concentric spheres is proportional to

A

`((r_2-r_1))/((r_1r_2))`

B

`ln ((r_2)/(r_1))`

C

`(r_1 r_2)/((r_2-r_1))`

D

`(r_2-r_1)`
