If \( n \) represents the actual number of deflections in a converted galvanometer of resistance \( G \) and shunt resistance \( S \). Then the total current \( I \) when its figure of merit is \( K \) will be
(a) \( \frac{K S}{(S+G)} \)
(b) \( \frac{(G+S)}{n K S} \)
(c) \( \frac{n K S}{(G+S)} \)
(d) \( \frac{n K(G+S)}{S} \)
