Match the List $I$ with the List $II$ from the combination shown. In the left side (List $I$) there are four different conditions and in the right side (List $II$), there are ratios of heat produced in each resistance for each condition :
| List $I$ | List $II$ |
| $(I)$ Two wires of same resistance are connected in series and same current is passed through them | $(A)$ $1:2$ |
| $(II)$ Two wires of resistance $R$ and $2R$ $ohm$ are connected in series and same $P . D .$ is applied across them | $(B)$ $4:1$ |
| $(III)$ Two wires of same resistance are connected in parallel and same current is flowing through them | $(C)$ $1:1$ |
| $(IV)$ Two wires of resistances in the ratio $1: 2$ are connected in parallel and same $P . D .$ is applied across the | $(D)$ $2:1$ |
