How is time shifting represented in case of periodic signal?

A. If x(t) is shifted to t<sub>0</sub>, X<sub>n</sub> is shifted to t<sub>0</sub>
B. x(t-t<sub>0</sub>), Y<sub>n</sub> = X<sub>n</sub> e<sup>-njwt0</sup>
C. X<sub>n</sub> = x(t-t<sub>0</sub>), Y<sub>n</sub> = X<sub>n</sub> e<sup>-njwt0</sup>
D. X<sub>n</sub> = x(-t<sub>0</sub>), Y<sub>n</sub> = X<sub>n</sub> e<sup>-njwt0</sup>
Answer» D. X<sub>n</sub> = x(-t<sub>0</sub>), Y<sub>n</sub> = X<sub>n</sub> e<sup>-njwt0</sup>
