Three resistances $ R, 2R$ and $3R$ are connected in parallel to a battery. Then

Question

$\begin {array} {1 1} (A)\;The \: potential\: drop \:across \: the\: 3R \: is \:maximum \\ (B)\;The\: current\: through\: each \: resistance\: is\: the\: same \\ (C)\;The \: heat\: developed\: in\: 3R \: is \: maximum \\ (D)\;The\: heat\: developed\: in\: R\: is \: maximum \end {array}$
