Below

Explanation:

y=tan(x-pi/2) is basically y=tanx shifted to the right by pi/2
That means that the entire graph including the asmpytotes move to the right by pi/2 units.

graph{tanx [-10, 10, -5, 5]}
Above is y=tanx

graph{tan(x-pi/2) [-10, 10, -5, 5]}

Above is y=tan(x-pi/2) If you focus on (0,0) in the first graph, you will notice that in y=tan(x-pi/2), it has shifted to the right by pi/2 units or approximately 1.57 units to the right.
