The circuit shown in figure (ii) is properly connected. In other figures, the connections are not correct. For example: In figure (i), the voltmeter is connected in series and not in parallel. Similarly in figure (iii), an ammeter is in parallel which should be in series.

In figure (iv), the negative terminal of battery has been connected to the positive terminal of ammeter whereas it should be connected to the negative terminal and not positive terminal of the ammeter.
