can some one please confirm if my understanding is correct =

I think in order to refer time we need "when" not "which".

Secondly, we know this =

which + SINGULAR VERB will serve to refer to the nearest preceding singular noun.
which+ PLURAL VERB will serve to refer to the nearest preceding plural noun.

Based on our above knowledge it appears that which + was seems to refer to growth and this is not the intended meaning.

Option A
Option B
Option C
Option D
Option E

Again, we are down to =

verb form vs participle form.

determined by = modifier or participle.
differed = verb

but we are looking for modifier/participle, not a verb so differing should be ok.

Option E.

With the same form of ||'sm we can eliminate option C, which is presenting =

were determined || differing =
verb || participant in Option C. Hence discarded.

(A) which was determined by when the sun reached the observer's meridian and differing - which should be used twice (2nd one after and) + local times should have plural verb
(B) which was determined by when the sun reached the observer's meridian and which differed- local times should have plural verb
(C) which were determined by when the sun reached the observer's meridian and differing - which should be used twice (2nd one after and) for proper structure
(D) determined by when the sun reached the observer's meridian and differed - its seems that the sun reached and differed.. change in meaning
(E) determined by when the sun reached the observer's meridian and differing- Correct. the local times, determined by A and differing from city to city.
