\({A, B}~\text{and}~{C}\) are voltmeters of resistance \(R,\) \(1.5R\) and \(3R\) respectively as shown in the figure above. When some potential difference is applied between \({X}\) and \({Y},\) the voltmeter readings are \({V}_{A},\) \({V}_{B}\) and \({V}_{C}\) respectively. Then:

        

1. \({V}_{A} ={V}_{B}={V}_{C}\) 2. \({V}_{A} \neq{V}_{B}={V}_{C}\)
3. \({V}_{A} ={V}_{B}\neq{V}_{C}\) 4. \({V}_{A} \ne{V}_{B}\ne{V}_{C}\)
