Two rods of same length and cross section are joined along the length. Thermal conductivities of first and second rod are `K_(1)` and `K_(2)`. The temperature of the free ends of the first and seconds rods are maintained at `theta_(1)` and `theta_(2)` respectively. The temperature of the common junction is

A

`(theta_(1)+theta_(2))/(2)`

B

`(K_(2)K_(2))/(K_(1)+K_(2))(theta_(1)+theta_(2))`

C

`(K_(1)theta_(1)+K_(2)theta_(2))/(K_(1)+K_(2))`

D
