An interval is BETWEEN two things. Hence options B, D and E can be eliminated.

A preposition must be followed by a noun. Hence "between" also should be followed by a noun. A concrete noun, when it exists, is preferred to a gerund. Hence option C (noun "passes") is better than option A (gerund "passing" - moreover a plural "passings" should have been used because an interval is between two things).

(A) between passing
(B) of passing
(C) between its passes
(D) of its passes
(E) as it passes

completely lost it please can any 1 explain

in A. between need to be followed by countable noun such as " two points in time and space, two dicisions...". passing can not meet this meaning requirement. a is wrong.
in B , "interval of passing" . this means the passing is an interval of many years. this meaning can be correct but in this context of this question it is not correct.
in E. similar to B.
in C "interval of its passes" . this mean many "passes" have one interval of many years. in this context , this meaning is not logic.

The above post already clarifies why C is correct - probably you missed it: because-halleys-comet-changes-orbit-slightly-during-the-84392-20.html#p1784877

In case you still have doubt, please post again.

Not necessarily, any number of passes more than 1 pass can be denoted by plural "passes" - From the context of the sentence ("interval between"), it is clear that 2 consecutive passes are referred to.

Please refer to the post just above yours that explains why C is the correct answer.

accordinng to Oxford dictionary, "interval between" two events and "interval of" a period of time
eg: interval between a flash of lightning and the sound of thunder, interval of half an hour

I have initially chosen E, while the correct answer is C, but now I see the difference.

Because Halley’s comet changes orbit slightly during the seventy-six-year interval between passing close to Earth, it may veer onto a collision course with a planet sometime in the distant future.

(C) between its passes - implies that the comet changes its orbit between times it passes close to Earth, which makes more sense. I.e. scientist have measured comet's orbit twice in 1900 and then in 1976 at times it passed close to earth. They realized that the comet's orbit has changed between 1900 and 1976
Vs.
(E) as it passes - implies that the comet changes it's orbit in a very moment it passes close to Earth, which makes no sense. Comet can't change its orbit instantly in the moment it passes close to Earth.

Between...To... is not correct idiom. According to stanards which I have read in many books, correct idiom should be: Between....X and Y.
