For a cell, the graph between the potential difference $(V) $ across the terminals of the cell and the current $(I)$ drawn from the cell is shown in the figure. The $e.m.f.$ and the internal resistance of the cell are
  • A$2\,V$,   $0.5\,\Omega $
  • B$2\,V$,   $0.4\,\Omega $
  • C$ > 2\,V$,   $0.5\,\Omega $
  • D$ > 2\,V$,   $0.4\,\Omega $
