A battery of $emf\: E$ and internal resistance $ r$ is connected across a resistance $ R.\: R$ can be adjusted to any value greater than or equal to zero. A graph is plotted between the current through the resistance and the potential difference across it. Select the incorrect alternative


$\begin {array} {1 1} (A)\;Internal\: resistance\: of\: the\: battery \: is\: 5\: ohms \\ (B)\;EMF \: of\: the\: battery\: is\: 10V \\ (C)\;Max.\: current \: that \: can \:be\: taken\: from\: the\: battery\: is\: 2A \\ (D)\;The\: graph\: shown \: in\: the\: figure\: is\: inappropriate \: and \: can \: never\: occur \end {array}$
