Which of the following equations will deseasonalise a time series, where T, C, S and R are respectively the trend, cyclical, seasonal and random variation components of the time series?
A) (T $\times$ C $\times$ S $\times$ R) / T = C $\times$ S $\times$ R.
B) (T $\times$ C $\times$ S $\times$ R) / C = T $\times$ S $\times$ R.
C) (T $\times$ C $\times$ S $\times$ R) / S = T $\times$ C $\times$ R.
D) (T $\times$ C $\times$ S $\times$ R) / R = T $\times$ C $\times$ S.

(T $\times$ C $\times$ S $\times$ R) / S = T $\times$ C $\times$ R.This equation deseasonalises a time series by dividing the original time series by the seasonal component (S). This removes the seasonal variation from the time series, leaving only the trend, cyclical, and random variation components.
