Two sheets of thickness \( \mathrm{d} \) and \( 3 \mathrm{~d} \), are touching each other. The temperature just outside the thinner sheet side is A,
\( \mathrm{P} \) and on the side of the thicker sheet is \( \mathrm{C} \). The interface
W. temperature is \( \mathrm{B} \). \( \mathrm{A}, \mathrm{B} \) and \( \mathrm{C} \) are in arithmetic progression, then the ratio of thermal conductivity of thinner sheet and thicker sheet is
(a) \( 1: 3 \)
(b) \( 3: 1 \)
(c) \( 2: 3 \)
(d) \( 1: 9 \)
