Cho hàm số \(f\left( x \right) = \ln 2020 - \ln \left( {\dfrac{{x + 1}}{x}} \right)\). Tính \(S = f'\left( 1 \right) + f'\left( 2 \right) + ... + f'\left( {2020} \right)\).
A.\(S = 2020\)
B.\(S = 2021\)
C.\(S = \dfrac{{2021}}{{2020}}\)
D.\(S = \dfrac{{2020}}{{2021}}\)
A.\(S = 2020\)
B.\(S = 2021\)
C.\(S = \dfrac{{2021}}{{2020}}\)
D.\(S = \dfrac{{2020}}{{2021}}\)
