The temperature drop through each layer of two layer
\( \mathrm{P} \) furnace wall is shown in figure. Assume that the external

W temperature \( T_{1} \) and \( T_{3} \) are maintained constant and \( T_{1} \) \( \mathrm{T}_{3} \). If the thickness of the layers \( \mathrm{x}_{1} \) and \( \mathrm{x}_{2} \) are the same, which of the following statements are correct.
(a) \( \mathrm{k}_{1}\mathrm{k}_{2} \)
(b) \( \mathrm{k}_{1}\mathrm{k}_{2} \)
(c) \( \mathrm{k}_{1}=\mathrm{k}_{2} \), but heat flow through material (a) is larger then through (b)
(d) \( \mathrm{k}_{1}=\mathrm{k}_{2} \) but heat flow through material \( (a) \) is less than that through (b)
