(A) between passing
(B) of passing
(C) between its passes
(D) of its passes
(E) as it passes
The answer is C.
I have seen this earlier. Here is the response of Stacy Koprince from some other forum
This source is a poor source from which to study. Some non-native English speakers based out of somewhere in Asia basically pirated a bunch of questions from old paper-based GMATs but the questions are filled with typos and errors, often to the point that none of the answer choices is good or the question has been garbled so that it is no longer sufficiently GMAT-like. If you want to study from old paper-based GMAT tests, at least go buy clean copies from mba.com. (Though, really, those are so old that I don't recommend them as a good source for study, either.)
This one is an example of one in which all of the choices are poor. Something got lost in translation here.
We do need "between" because we're talking about an interval. An interval is between two things (or, in this case, between two passes). So that eliminates B, D, and E
Is C perhaps supposed to say "between its passes"? Below, it says "between it passes" and that's obviously not right. If it is supposed to say "between its passes" then I guess that's the closest thing to a right answer, but - really - I wouldn't even study this one. It's not sufficiently GMAT-like.
