Consider two rods of same length and different specific heats (`S_1, S_2`), conductivities (`K_1, K_2`) and area of cross-sections (`A_1, A_2`) and both having temperature `T_1 and T_2` at their ends. If rate of loss of heat due to conduction is equal, then :-

A

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

B

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

C

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

D

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