A wide sense stationary random process X(t) passes through the LTI system shown in the figure. If the autocorrelation function of X(t) is RX(τ), then the autocorrelation function RY(τ) of the output Y(t) is equal to

• A. 2RX (τ) + RX (τ - T0) - RX (τ + T0)
• B. ​2RX (τ) - RX (τ - T0) - RX (τ + T0)
• C. ​2RX (τ) + 2RX (τ - 2T0)
• D. ​2RX (τ) - 2RX (τ - 2T0)
