Two rods A and B have lengths `l_1 and l_2.` Each rod has its ends at temperature `T_1 and T_2` Radii fo cross section of the two rods are same. The condition for equal flow of heat through those two rods is `(K_1, K_2` are thermal conductivities of two rods)
A. `K_1 I_1 =K_2 I_2`
B. `K_1 I_2 =K_2 I_1`
C. `K_1 = K_2`
D. `I_1= I_2`
