You are given $n$ resistors each of resistance $r$. They are first connected to get the minimum possible resistance. In the second case,they are again connected differently to get the maximum possible resistance. Calculate the ratio between minimum and maximum values of resistance so obtained.
- A$n^2$
- B$\frac{1}{n^2}$
- C$\frac{1}{n}$
- D$n$
