24 identical cells, each of internal resistance \( 0.5 \Omega \), are arranged in a parallel combination of \( n \) rows, each row containing \( m \) cells in series. The combination is connected across a resistor of \( 3 \Omega \). In order to send maximum current through the resistor, we should have
(a) \( m=12, n=2 \)
(b) \( m=8, n=3 \)
(c) \( m=2, n=12 \)
(d) \( m=3, n=8 \)
