12 cells, each of emf `1.5 V` and internal resistance of `0.5 Omega`, are arranged in `m` rows each containing `n` cells connected in series, as shown in the figure.
Calculate the values of `n and m` for which this combination would send maximum current through an external resistance of `1.5 Omega`.
Options:
(a) n = 6,m =2
(b) n =2, m = 6
(c) n =2,m =2
(d) n = 3,m=2
