0A composite slab consists of two slabs \( A \) and \( B \) of different materials but of the same thickness placed one on top of the other. The thermal conductivities of \( A \) and \( B \) are \( k_{1} \) and \( k_{2} \) respectively. A steady temperature difference of \( 12^{\circ} \mathrm{C} \) is maintained across the composite slab. If \( k_{1}=k_{2} / 2 \), the temperature difference across slab \( A \) will be :
(A) \( 4^{\circ} \mathrm{C} \)
(B) \( 8^{\circ} \mathrm{C} \)
(C) \( 12^{\circ} \mathrm{C} \)
(D) \( 16^{\circ} \mathrm{C} \)
