Firstly, I can't understand where did you find the ranges ( 0 - 1), ( 2 - 3), (4 - 5), (6 - 7), (8 - 9) ?

Read the statement -
As I am a student I study for D days and go on a date with my available girlfriend at every Dth day.

So I will search for a girlfriend on day 2, 4, 6, 8, 10, ............................
And my available ranges are [0, 3], [5,8]

1st time I won't have any girlfriend is on day 4.
So, the answer is 4.
If you still can't understand don't hesitate to send me a private message.
