A thin uniform wire AB  of length 1 m, an unknown resistance  X and a resistance of 12 straight capital omega  are connected, by thick conducting strips as shown in figure. A battery and a galvanometer (with a sliding jockey connected to it) are also available. Connections are to be measure the unknown resistance  using the principle of Wheatstone bridge. The appropriate connections are.
