A small block slides down on a smooth inclined plane, starting from rest at time \(t=0\). Let \(S_{n}\) be the distance travelled by the block in the interval \(t=n-1\) to \(t=n\). Then, the ratio \(\frac{S_{n}}{S_{n+1}}\) is :
A \(\frac{2 n-1}{2 n}\)
(B) \(\frac{2 n-1}{2 n+1}\)
c \(\frac{2 n+1}{2 n-1}\)
D \(\frac{2 n}{2 n-1}\)
